oh man..if you havent tried spwaw, you are going to LOVE this...
I'm in the middle of the "Lost victories" mega campaign...over 200 battles where you take your troops from June 22 1941 to the Soviet winter offensive in 42...You have to buy that one though, but it is well well worth it.
Or try the Stalingrad campaign with something like 40 battles.
If you want a game, let me know. But you should take a couple of days to get to know the game first, stuff like the command and control system can be hard to get into.
Spwaw is built on the SP3 engine, but it is with the SP scale (one vehicle, one squad, one gun). I've been playing spwaw for over two years, and Im still playing it.
