Just a quick note on the things I have run into while playing the 3C beta.

1) Crashes seem to occur frequently.  One of them was when I hit next turn, another when I double click something for more information.  The crashes freeze my entire system, I can't alt-tab or windows button out of the game and am forced to power off / on.  I was doing a 1 vs 1 on a small random map.

2) A lot of the graphics were foggy looking.  I read someone elses post that disabling dynamic lighting solved this, and it does.  I'm currently running 1920 x 1080 or its equivelent on my Gforce / Nvidea 9000 series 1 gig ram video card, Dell XPS gaming machine.

Besides the stability / crashing, the game seems great so far.
