Capturing planets, a question of practicality.

[couslee]

Another simple strategy you can apply to help conquered planets not start out rioting, is get the planets first. If you capture a planet that is angry or rioting, there is a reason for that. you inherit the mood of the people. for example
you enter a system, and mop up all the enemy ships, then move on to planet capture. The population has suffered a lot of anger increases because of enemy ships in sector, battles lost, ships lost, ect.. If you take the planets first, then mop up the enemy ships, you get two benefits. One, being they have not had all the battles lost anger increases, AND they get the anger decreases by your battle victories in that same sector. take the planets first, it makes a huge difference in alien happiness levels. And don't forget to leave enough troops behind to offset the "20". If you capture a planet and the first build order on emergency build is 6 troops. leave four of your invaders behind to act as police. I rarely have have to build UPCs doing this. So get the high pop ones first, then the smaller pop planets, then the Ai ships. Use intel to enemy ship supply drain and engine damage to stop them from attacking you while you grab the planets. then go mop-up the derelicts.

Try it, you will be glad you did.
