The full game of this is getting released today in the US (09/14/06). It really is a fantastic game and I advise anyone with any interest in RTS gaming to check it out.
Firstly the graphics are incredible; the explosions look amazing, the units are rediculously detailed and generally it looks awsome.
Physics are equally good. All units have realistic ragdoll physics and the environment is fully destructible.
Last but certainly not least the gameplay mechanics work really well. You get resources based on how many capture points you have but also once you capture a point you control that territory. It's hard to explain but this not only gives you a front line but also allows you to cut supply lines of your enemy. It's alot of fun reinforcing your frontline with tank traps, barbed wire, bunkers, MG nests, mortar teams and just about every other WW2 prop you can think of.
Other small touches like how MGs, mortars, artillery, anti-tank guns ,etc remain on the floor once their team is killed allowing you to take control of them and turn them on the enemy.
