Yea, had my first look at galciv3 yesterday, started a game and was almost immediately thwarted by no end turn button!
Looked in the keyboard assignments and i can see which key it is... press it and no end turn, pop back to planet where i think it wants me to start production?? Experience from Galciv2 tells me that your not supposed to start building anything for some time or your finances get sucked into and ever expanding black hole of disaster..... is Galciv3 so different?
Anyway, I'm sure there is a simple answer, but meanwhile, i ended up starting a new game of Galciv2, ah, that seems much better thanks.
