I'm not so impressed. Looks awesome and plays great on my PC, but not my cup of tea...
I totally appreciate the work Massive Ent. has put into the game. All the bells and whistles work great, but overall, I'm not too keen on the command mechanism and I find "floating" around the world a little too tasking. I also got the feeling that I can never die! I've stopped playing the game after 20mins because I didn't find it challenging. I know that the MP mode is a lot of fun, but for now my impression of the game is just average. Wait, I'll tell you one thing, the graphics are awesome (DX10), the setting is sweet and the voice over is ok. One more good thing - the fact that it's WW3!
That said, for those of you that really enjoy RTS games I'm sure you'll love it, everyone in my group of friends that has played the game (both SP and MP) has stated it's an awesome game. I will give it another try this weekend...put in about an hour or so. My conclusion: If you are a FPS fan like myself, then WIC isn't for you.
