I had Pz Command:Ostfront but it's not quite as graphically good looking as CMx2.
On the plus side it covers the entire Ost war 1941-45 and you get kool snowy landscapes each winter, the winter attempt by a German battlegroup to relieve Stalingrad is especially dramatic.
Virtually every type of German/Russian tank/gun/infantry units that were used in the war are in the game.
There's also a slow-motion replay feature where you can replay and analyse what went on during the turn.
Overall I'd rate it about the same as CMx2 complexity-wise, but I was put off by its poorer graphics.
