What DRM is in Dominions 3?

[CthulhuDreams]

Basically it's CD-Key only. They are beating copy protection by

A) Designing a CD-Key generation algorithm that is fairly complex

B) Slowly adding more of the validation checks they originally designed to each subsequent version - you can think of this as the key generator having 20 'rules' and each patch has checked for an additional 'rule' so pirate keys that work with an earlier version don't work after being patched

C) 'Soft failing' for CD key checks that makes it very difficult to automate any testing

It is quite clever, but relies on the game being pretty niche and frequent patching to be effective. Overall a very 'user friendly' copy protection system that doesn't require aggressive DRM.

Not that I care one way or the other, but do you have any evidence for this? They do more checking each patch? Wouldn't have thought they'd bother.

There is some evidence on these forums that supports that theory.

I love how some multiplayer games post-patch saw a large amount off players suddenly drop-out because their games stopped working.

I loved how some of those were the loudest and rudest in demanding a new patch, then find out they cant play with it. Cant complain, the patches and upgrades are all free. And its not like that is WHY they put out a patch. They do it for real game reasons. They just try to remember to toss in a new DRM section each time.

The problem with free things on the net is that people forget how to pay for free things. Didnt your Mommy teach you the power of please and thank you?"
