Hidden and Dangerous 2. One of the most realistic WWII shooters/strategy game I’ve ever played. It’s a bit dated now, but I think it’s far better than CoD or Medal of Honour.
I still play Battlefield 1942 a lot. OK, it’s very outdated, but the gameplay is fantastic and you have many multiplayer servers.
Another game that’s nice is the freeware Wolfenstein. Not the best, but it sure is fun to play:D
At the moment I want to try Red Orchestra, a game based totally on the russian front. I’ve heard many good stories of it and seen some movies and screenshots. It really looks great!!
Many games, and you can only play one at the time 😉
