Battlefield 1942
I am completly addicted to this game,it was one of the first games i purchased when i got highspeed internet connection,the only trouble i really get from playing this game is finding a good 'non lagging' server. BF 1942 is a game mainly designed for the online gamer in mind although a solo player game is included it is pretty mundane and has a few bugs,however the multiplayer is second to none a must for any online FPS (First Person Shooter) fans who enjoy team based shooters.
