I play games from time to time, but I usually play them for narrative and all, like say... an interactive movie.
Currently I'm still playing Fallout: New Vegas. Could go to the endgame, but I just like wandering around, exploring new stuff. And besides that I play Magic the gathering: Online... not the Duels of the planeswalkers thing, but the stuff with virtual cards. Play tournaments sometimes. Used to play that with real cards, but there isn't a lot going on in my area so MTGO is a better way to stay into the game.
But yeah... games, I tend to go more into shooters, as long as they have some good setting to it. I liked Hellgate, which I got into after I read the comics and books. I enjoyed Fallout 3 and I liked both Bioshocks. Half-life 1 & 2 are games I enjoyed... but yeah, perhaps the kinda general stuff. But if it's in a own "universe" and has more to it than just "fancy guns" I might be interested. I'm still looking forward to playing Deus Ex 3, but I guess my graphicscard wont let me. Same goes for Rage... and I doubt the new Batman game would be smooth. But I'm still planning on upgrading to a Radeon 5800+ or 6800+ somewhere series depending on budget. 8800 GT's are fine... correction; were fine, heh. I enjoy some RTS games like The command and conquer series which was quite awesome (except for the recent stuff :') )and I liked the Dawn of war games (DoW2 didn't do much for me). I used to grind a lot online with Diablo 2 about 10 years ago or so, so for nostalgia sake I'm looking forward to D3.
Funny you mention TF2, I used to play that through steam quite a lot a year of 3 ago, but I only cared for that Store map, which, back then was the only team deathmatch thing. I tried other games like Quake and all, but they didn't really do it for me. Wacky stuff in TF is what got me hooked. Haven't installed it recently, but I might just do that somewhere soon... probably winter, heh.
As for other platforms... I used to own a 360. Still own, but it's broken... damn you 3-rings! I might try to fix it... after all, it can't work any less. But on consoles I tend to play beat 'm up games like Tekken, SFIV, Virtua fighter and stuff like that. Did the same as a kid when I had a SNES and the entire Mortal kombat thing going on. To kill some time I enjoy the Raw vs. Smackdown wrestlinggames as well. My thing with consoles kinda is... I put switch them on when someone is around, that's why I pretty much have something like that. I'm not that much of a lone gamer kinda person. And to some extent something like Tekken is quite easy to pick up for anyone (granted if you have it around you're prone in getting better at it) and you can have lots of fun just beating each other up, rather then someone sitting next to you while you slug out another mission in CoD.
Final platform; my DS, but I use it mostly for music creation. DS-10 is awesome. That being said, I do have a NES emulator on it and play some NES games on my DS. Primarily the Megaman games. Though I'm planning on getting a NES for the heck of it.
But no actually, I'm not a big gamer. Spend roughly... an hour a day or so on actual games. Alright.. might be 2, heh... but that's pretty much it.
