I think it is a good game. However, I am still waiting for the first patch
Tried it out a few days ago and thought it could run a little bit better. But it is more than a graphics demo. The AI is quite good, actually. I dont understand why some people criticize it for bad reactions. The enemy soldiers react in an intelligent way, use flanking strategies and such... it may be that this is also performance-related (if you dont have enough mhz, it turns down ai behavior, perhaps)
