Bidding System - Specifics
 
Each player starts with 40,000 population in their capital. They then bid population on (number of players) nations. They cannot bid the same amount on two different nations. The bidding is entirely secret between the different players.

The highest bid is assigned to the nation chosen, one at a time, until everyone is assigned to a nation.

In the event that the highest bid is a tie, if it is for two different nations, no problem.

If the highest bid is a tie and it is for the same nation, ties are settled thusly:

total all bids for the next-choice nation of each of the competitors (or the nation after that if they are the same.) The player whose second choice nation has a lower total bid wins the tie. In the event that this is also a tie, move on to the next choice for each player. A choice of "no nation" (because you ran out) has an infinite bid. If the tie still cannot be resolved, resolve it randomly, and the loser wins all ties and pays only 75% for all their remaining bids.

Now, total the bids (including unused bids) on all the nations that were assigned. "Rank" the nations by *increasing* value of total bid. In the event of a tie, all nations have the higher rank.

Nations ranked 1 through (number of players / 2, rounded down) get to pick prizes from the following list. The player ranked 1 gets to make (number of players / 2, rounded up) selections, rank (n+1) makes 1 fewer selections than rank (n).

Prizes:
* Additional national troops equal to 50% of your starting army strength. For every two times you take this, you also get an additional starting commander (not scout).
* Surprise me! You get an additional scout, with randomequip 4.
* Capital upgrade. Increase the admin of your capital by 5%. You can pick any fortress that fits the bill. Max admin possible is 60%.
* Additional capital site: your capital can contain either an Iron Mine, or a site of your choice with a gem income of 1 and no other effects. You obviously can't have more than 4 sites in your capital.

EXAMPLE 4 player bids:

DrPraetorious bids:
Niefelheim 12000
Abyssia 5001
Sauromatia 5000
Arcoscephale 4999

Llamabeast bids:
Sauromatia 1204
Niefelheim 1203
Caelum 1202
Lanka 1201

Tyrant bids:
R'lyeh 4
Caelum 3
Helheim 2
C'tis 1

JayThomas bids:
R'lyeh 1101
Helheim 1100
T'ien Ch'i 1099
Lanka 1098

Firstly, I get Niefelheim with my bid of 12,000. Total bids on niefelheim are 13,303.
Then, Llamabeast gets Sauromatia with his bid of 1204. total bids on Sauromatia are 6,204.
JayThaoms gets R'lyeh with 1,101. Total bids on R'lyeh are 1,105.
Finally, Tyrant gets Caelum with his bid of 3. Total bids on Caelum are 1,205.

JayThomas has the lowest total bid, so he gets two prizes. Tyrant has the second lowest total bid, so he gets one prize. Neither I nor Llamabeast get any prizes.

The system is *meant* to be used in large games, with >9 players. This way, someone might take Marverni, hoping to get a population of 39,996 and five prizes (which would be quite a plum, potentially.)

Does this seem fair to everyone?

Re: Bidding System - Specifics
 
You lost me. I'll have to read this again after more caffeine. Why is JayThomas a lower total bid than Tyrant. Are your calculations right, or am I just exceptionally slow today ? http://forum.shrapnelgames.com/image...s/confused.gif

Re: Bidding System - Specifics
 
Total pop bid on R'lyeh is 1,105 (=1,101+4) <-- JayThomas won R'lyeh.

Total pop bid on Caelum is 1,205 (=3+1202) <-- Tyrant won Caelum.

1105 < 1205 so JayThomas has the lowest total bid.

What starting population would Niefelheim have? 28000, or 13000? (Do you pay just your bid for the nation you won, or the sum or your bids?)

Re: Bidding System - Specifics
 
So if there are 10 nations, each player has to bid for 10 nations, he can not just bid for one nation?

DrPraetorious April 19th, 2007 06:16 AM

Re: Bidding System - Specifics
 
wfb - Niefelheim would have a population of 28000 (you only pay the bid that actually goes through.)

LoloMo - you absolutely must bid for 10 nations. You could bid something like:

nationA 12,000
nationB 9
nationC 8
...
nationJ 1

Note that since you only pay the winning bid, and you want the total bids for opponent's nations to be high, it is to your advantage to bid something on all nine nations, provided you actually do get your first choice.

LoloMo April 19th, 2007 07:22 AM

Re: Bidding System - Specifics
 
Seems like a workable system. The bidding process is like a game unto itself, each bidder has to think really carefully.

When do we test this out? =)

LoloMo April 19th, 2007 07:30 AM

Re: Bidding System - Specifics
 
What happens if a player bids the highest for say 3 nations?

Micah April 19th, 2007 07:48 AM

Re: Bidding System - Specifics
 
Lolo-

He gets the one he bid the most on (and he can't bid the same amount on 2 nations).

My question is what do you do about LE Ermor? They don't really care much about their capital's population.

Likewise, some resource-intensive nations might get skewed, since you have to rely on other people bidding low to get the iron mine bonus, which won't happen if people all decide to bid fairly high on, say, MA Ulm, realizing that they can take a lower gold:resource ratio and do fine...the person that ends up with them will end up in a bad spot not because people all thoght Ulm was awesome enough to overcome, but because they thought they'd get some bonuses to compensate for it being crappy.

Finally, people tend to have nation preferences that are independant of balance. Some people simply don't want to play, say, LE Rlyeh because they don't like the feel of it, which again will skew the bidding, giving the person that does end up with it a big boost since everyone else bid low to avoid getting it.

I like the idea a lot, and I know every system has flaws, so I'm not trying to nitpick, I'm just pointing out what I see as potential problems so that maybe someone can come up with a tweak to fix them, or just tell me I'm being overly anal. =)

LoloMo April 19th, 2007 08:06 AM

Re: Bidding System - Specifics
 
Micah, I think if lots of people bid high on MA Ulm in your example, then it probably means Ulm with the iron mine bonus is pretty much in demand.

To prevent extreme imbalances due to LE Rlyeh theme unpopularity for example, a suggestion would be to have a second or third round of bidding, where you can adjust your bid upwards (upwards only never downwards, and by a minimum of 30% higher than the winning bid).

The more rounds of bidding the lower the minimum bid increase can be. But a lot of work to tally it though unless it is automated.

Edit: Can also limit the second and successive bidding rounds to submitting only one increased bid per player.

Re: Bidding System - Specifics
 
In the past I've proposed a bidding system based on Pretender Points - as they are worth about the same to every nation - were population might not be.

I've always liked the idea of a bidding system though.

Ironhawk April 19th, 2007 02:09 PM

Re: Bidding System - Specifics
 
Seems like a decent Sealed-Bid Auction protocol. I like how you are betting population, that was a nice touch. But you should keep in mind that a player could completely ruin thier nation in this fashion, ie: I bid 40,000 (all my pop!!) for Abysia. It might seem like poetic justice to rob that person of all thier pop, but it will make for a bad game due to the power vacuum it will create.

Additionally, I am not sure the prize system functions as you add more players. Consider an 18 player game (that is max in dom3, i think?). If I am the least bid on nation, then I will receive 9 prizes. What happens if I choose the troop prize every time? I will end up with 450% more troops than everyone else!

DrPraetorious April 19th, 2007 02:11 PM

Re: Bidding System - Specifics
 
Pretender points are not worth the same to every nation - LE Ermor, for example, could care less, frankly.

The issue with bidding pretender points is that it is difficult to engineer. You have to figure out some way to open people's pretender files and look at the contents. This bidding system is done entirely with the map editor.

I agree that water-based nations are a problem. It could be as simple as: water nations do not ever get the bonuses (but you still have to bid on them.) It should also be noted that since I use maps with fixed #s of start sites, the # of water positions would be fixed - so if there's a water start site, everyone must bid *something* on a water position, in case they are stuck with it.

Re: Bidding System - Specifics
 
Wouldn�t it be better to implement a second prize auction?

That way there would be no need to bid in a strategic way and you could simply bid the maximum amount which a nation is worth to you. Might also provide more insights into the way players perceive nation balance.

DrPraetorious April 19th, 2007 04:35 PM

Re: Bidding System - Specifics
 
My only problem with that is that people will have a tendency to bid on their friends, or on *players* they think are not a threat. Also, you have to handle the second round of bidding, which takes extra time.

How's this for prizes -
People # (players / 4) or less get 3 prizes.
People # (players / 2) or less get 2 prizes.
People # (players * 3 / 4) or less get 1 prize.
People above the 75% get no prizes.

For 10 players, that would be:
1,2 - 3
3,4,5 - 2
6,7 - 1
8,9,10 - 0

How's that?

Micah April 19th, 2007 05:18 PM

Re: Bidding System - Specifics
 
I do like the pretender point system better than the population one, actually. Granted LE Ermor's points aren't worth as much as other nations, but that's ok, since Ermor's bids only interact with other bids for Ermor. The customization that pretender design allows for is also more versatile than a simple population adjustment (although resource-needy nations can't take production 4 no matter how many points they have). The one thing I don't like about the pretender-bid system other than the extra administration hassle of god-checking isn't a balance issue. You can only bid lower for the pretender points, so you're basically bidding on how much of a handicap you can live with, and everyone knows that getting new toys is a lot more fun than losing the ones you have.

Ironhawk's point about large games with lots of bonus prizes is also very valid, a 450% larger starting force for being the last nation is a pretty hefty bonus compared to the guy that got nation number 10 with no bonus picks. I don't like the introduction of so much randomness into the bids, either, because being able to bid on Ulm with a mine is vastly different than Ulm without a mine, and there's no sure way to tell which one you'll get when you bid. In essence the bonus becomes more important than the "real" bid on population.

Offering the prizes in trade for population (say 2500 pop for an iron mine, maybe) seems like a good compromise, so you could control what setup you'd get. To control for other people's perceptions of the power of a nation how about this: A nation's starting population is equal to

40,000 - (.5 of the winner's bid + .5 of the average of other bids on that nation)

This keeps the bidding for a nation relative only to its own strengths, so everyone can go ahead and bid max for LE Ermor and it won't really impact the other nations. It also gives a much more gradual balance curve, since with the bonus picks a nation can get a significant bonus because of a very small difference in bids, while with this system two nations that are bid on nearly the same will have nearly the same starting bonus. By halving the winner's bid it ensures that when you pick a nation you'll have at least as many resources as you bid (which is essential to formulating a workable strategy), but you could have up to 150% as much as you bid once the results are in if everyone else thinks your nation sucks.

Just some more thoughts.

Oh, and Ironhawk, bidding 40,000 on Abysia would be about the same as suiciding your starting army and sitting there waiting to get taken over, which people can do without any help from a bid system or anything else...if someone wants to ruin the game by not playing it's not really very hard to do.

Ironhawk April 19th, 2007 05:28 PM

Re: Bidding System - Specifics
 
Yes, they can ruin themselves without the help of a bidding system. But this bidding system particularly lends itself to people shooting themselves in the foot since it effects thier starting population.

Micah April 19th, 2007 05:34 PM

Re: Bidding System - Specifics
 
Yes, but at least whoever kills them will get a crappy province out of it this way, instead of one with high population if someone plays poorly on their own...the bid system is also only really useful for competitive play, so new players shouldn't be messing with it right off the bat until they have at least a loose grasp of the power levels of the different nations (that's one of the other concerns I have...people not bidding on a nation because they don't know it well enough to play it, and not because it's too weak, leading someone to possibly get it cheaply, like I mentioned for Rlyeh)

DrPraetorious April 19th, 2007 05:51 PM

Re: Bidding System - Specifics
 
Okay, in case it is an issue: the maximum possible bid is 20,000.

I don�t really get what you mean.
I�d propose the following mechanism for a second prize auction:
1. Each player makes bids for all nations.

2. Assign nation 1:
The nation which got the highest total bid gets assigned to the player who made that bid. That player has to pay an amount in population equal to the second highest bid.
Then the remaining bids of that player and the remaining bids for the nation he chose get removed from the bidding process.

3. Assign nation 2
Repeat step 2 with the remaining nations and bids until all nations are assigned.

Unless I�m really missing something it should be optimal for each player to bid his reservation value on each nation.
