I play when I can, my kids come first.
I am strictly a PC user, won't buy into platform gaming (unless someone gives me their old system, lol), I did however buy a Wii for my kids (and just had to get Budokai Tenkaichi 2 for myself 
).
Can't stand that game developers hold back porting games to PC, as I feel the PC is still the greatest gaming platform ever. The PC gaming platform shall rise to the top again...

I play Crysis, Gears of War, Unreal Tournament III, Devil May Cry 4, BioShock, Call of Duty 4, Quake Wars, Halo 2, Assassin's Creed etc. with ALL graphic settings maxed out (sometimes gotta turn back tha AA, but hey I really don't miss it anyway as I'm actually not a big fan of antialiasing, to me it takes away from the game some if there is too much of it), wow they are pretty, but the AI in Crysis (at least the chickens offer some amusement)...
The most played game on my system is Shadworun, the FPS, not the RPG (I have read some of the books based on the RPG, and it does have great universe built up around it, I just am not all that into RPG's, though I would play a Shadowrun RPG video game), it is the most well balanced multiplayer game I have ever played. I also play Halo CE (custom edition) alot (my older daughter loves playing it with me), a bunch of old Half-Life 1 (pre-Source) mods, especially ESF (Earth's Special Forces) and Counter Strike and the like. I like the newer games to look at mostly, but keep going back to these old ones, just more fun ultimately, I guess.
REMEMBER:
It's not about the BEST choice you can make, it's about the LEAST crappy one that will ultimately prevail.
