I bought this game yesterday and it does not disappoint! It has some bugs and can seem amateurish (some English translations are exceptionally poor) but the gameplay is brilliant. Tank warfare is great, everything is taken into account. Where you hit the tank, armour thickness, shell velocity, armour sloping, everything. Infantry combat is also great, good bullet physics and realistic damage with squad based tactics. Air combat can be difficult at times but works out well and you can really feel a kick from the cannons. My biggest criticism would be the gun sounds, they just sound too weak.
For anyone who is in it for tanks/aircraft, here's what you get (can't remember full names/models without checking the game);
Germany:
Panzer IV
Panther
StuG III
King Tiger
Surprisingly no Tiger tank.
Soviet Union:
T-34/76
T-34/85
SU-85
IS-2
Aircraft;
Germany:
FW-190
Stuka
Soviet Union:
P-39
PE-2
