Warhammer as in the board game? If so then yes, I play Warhammer 40,000 and my main army is Space Wolves. I was really into it back in the day, I haven't played in close to a year though.
If you like older strategy games then you would probably really like Rise of Nations. I don't if anyone plays online anymore though, honestly the single player is so fun you really don't need online with it.
