Firaxis absolutely dropped the ball on this game. I have played since the first CIV and this is the most frustrating one of the series. My system far exceeds all requirements and I still cannot play on a huge map. At some level the number of units brings the game to an unplayable point. Large saved games won't even load. I have applied the patch and read user comments of other suggestions. It is actually amazing that they couldn't get a turn based game to play better than this. The sad part is the design of the game is wonderful, hands down the best of the series. I just don't think Firaxis has the skill sets to use and understand the 3D tools yet. I have played RTS games with ten times the units that perform better than this turn based game. 2K may have pushed the release date up, but the blame still falls on the game maker. This wreck is going back to the store.
