I think one of the things you guys should avoid on the demo version is a turn limit. In the SE4 Demo, I was annoyed to no end by the turn limit, where my empire would just be getting ready to fight and I would have only twenty turns left to do anything. Perhaps this annoyance is what they were seeking, so that I would be annoyed into buying the game, but it had the opposite effect. I saw that I was already reaching the "micro-management critical mass," at turn 100, and I was just getting started. But I will probably buy this game as soon as I've gotten a demo version to see what it's like and make sure it runs well on my computer. I'm looking forward to it!
