I played it yesterday for about 8 hours. I noticed that when stacking ships I get a ghost or several ghost anomolies posing as a space ship.
Also when I hold down the control key selecting ships to go into a fleet my mouse becomes Jittery in the game and hard to move like the game is having trouble multitasking doing more than one function at a time.
But so far its been a good game. I played against 5 doods set on normal/AI Normal - I do understand what the AI tries to do, it will go the same way you do for a while and just adds a ripple in your whole harmonious way of life. By them becoming a super power isn't that difficult when you're at influetial insurrection or whatever that is.
I play Rome Total War I love that game I played it for 38 hours str8!!!! I know what its like managing 72 cities and its difficult when they revolt but it is always controllable. I have a great Knack for Micromanagment.
