"Red Orchestra" mod for UT2004. It's a fantastically realistic FPS game. excellent graphics, surperb gameplay. you are not a true WWII gamer until you've played it.
"DOD: Source" will be great, since it'll be DOD but with better graphics.
"WWII Online", though extremely dated, is a wonderful and extremely realistic MMO WWII FPS game. THE most team-oriented game I have ever played. the only thing thats holding it back is the graphics, which are pre Half-Life quality at best. If they would were to update them, I think it would be a smash hit.
"Forgotten Hope" Mod for BF1942. It's what Battlefield should have been.
Hard at work on this side, let the truth magnify,
Devils can't stop me, but they damn sure try...
