Just a quicky tonight, silly windows

Next week Halo 3 comes out, then the week after that Zelda DS hits the handhelds. Despite my fond memories of headshots and trying to create strategies to womp my friends with, I'm going to end up playing more Zelda than anything for the next few weeks simply because I can play it while at work.
For being only 22, I sure feel old!
Which type of game do you most enjoy, and can you play it at work?

PS: you can cheat, and play bigger games at work, but it's harder bringing an xbox and TV in without attracting attention...
