Bloody Good Time.

Good game nobody's playing is almost an oxymoron. If the game's good somebody will always be playing it. And the replies to this thread are very much supporting it... people are recommending so much garbage here but I guess they're just too lazy to read anything else then the name of the thread. Good games never die.

Alien Breed (multiplayer not working)
Red Alert 3 (online login unavailable)

1)Spec Ops:The Line and 2)Lead and Gold. Too bad they're dead ..they are good games..

Unreal Tournament 2004 (it is the absolute masterpiece in the series for me)

Heroes of Might & Magic 3-4 (these were the best, after the 5th, the series lost it's charm for me)
