My favorite is CCV - Close Combat: Invasion Normandy. Don't waste your time playing the original game though, go online and get a mod for it.
I highly recommend the CCV mods:
- Gold, Juno, Sword
- Stalingrad
- Stalingrad der Kessel
- Winter War
- Okinawa
- Bloody Omaha
- Battle of Berlin
- Arika 40/41
- Muese
- and tons more

I am always on the look out for anyone that wants to play online.
