I don't play very many games but I do like the Grand Theft Auto series also. Definitely a guilty pleasure. I also enjoy sports like Hockey (ESPN), Football (ESPN & Madden* ) and Soccer (FIFA).
Like zire71man I love emulation. On my Mac I play MacMame (Arcade) and Power64 (Commodore 64 emulator). Most of the emulation I play around with is emulation of old computers.
We actually have all three major consoles but I rarely play them. I have an Xbox but still haven't bought the original Halo. You'd think from all the news about it every single Xbox owner bought a copy heh.
I was signed up for
Gamefly for a little while. It was a great way to try new games but I didn't play often enough to justify it so canceled it. It's a cool service though.
*Of course now that EA has an exlcusive license with the NFL I'll probably boycott Madden on principle
