I'd consider myself a hardcore gamer, vs a casual gamer.  I like my shooters, with good deep involving stories such as bioshock.  Team fortress 2 is my favorite multiplayer game.  I also like some RTS games.  I'm a PC gamer primarly and think it's the best platform for the games I play, and PC gaming is not nearly as expensive as everyone thinks.

My roommates have a console which is good for some games, such as racing, fighting or sports. However most racing games these days are single player only so I can't race them, and sports are okay but I suck at them and much rather play a shooter.
