It does sound very cool. Totally desructable surroundings. the building fall apart based on where explosions take place. The battle field changes and develops as you play, meaning that options open up the further you get into.
The PCG review really made it sound a hell of alot of fun. I'll report back with what i think when i get home, as you know Gil i love RTW too, so i can say how it measures up in comparison.
It's WWII based btw.
