Some tips

[Kundral]

I have recently gotten SE IV gold and I'm wondering if any of you can give some mid game tips...

If you've researched warp point openers, you can open a warp point to an enemy system and bypass their warp point defenses.

If you've researched fighters and you want to attack a lightly defended system, don't waste a whole fleet on it. Send in a couple of carriers and launch fighters in groups of 10 or 20 to take out planets. Much cheaper.

Firstly, colonise, colonise, colonise! Second, build a weapon platform on each planet fairly early, but do NOT fill the planet with them. You need room for fighters and troops etc. You also need to build new weapon platforms as your research improves and dump the old ones.
Later on when you have troops, you can load 5 into a colony ship then people and colonise. That way they have some minor immediate protection and are happier. Try and research in a balanced way, but I prefer to not research some weapons to avoid wasting research points. Pick 3 or 4 types and stick with them. W/P openers comes from 3rd level (?) stellar manipulation and costs a fair bit, so is a long way from getting. Not necessary early on anyway. The planet builder (level 2) is rather handy if there are a lot of asteroids around, it turns them into a planet!
Mines early on can save your bacon, later on become useless when the enemy can sweep 50+ in one go..
Apart from attack ships, you want a couple of defense ships in each fleet, equiped with PD (point defense) to knock out enemy missiles and fighters, and remember to build minesweepers....

I have develpoded my playing style from you tips and experimentation... thank you!

This isn't a mid-game tip, but something I begin early and continue throughout the game:

Build a few small transports and give them repeat orders to take population from your home world and deposit them on select planets that you colonize.

This helps those colonies grow a bit faster. And by the time the transports return for more people, the ones they took away earlier have been replaced. So you don't have to worry about your home planet being depopulated.

I also like to rely on satellites for warp point defense.

you prefer satilites I prefer mines and a base

[Artaud]

Mines are quite good early on, but by the mid-game your opponents will be sending sweeper-equipped ships to dispose of them with ease.

For me it's satellites, supplemented with defence bases.
