Not everyone has a gaming PC. I have both but I generally have more fun on xbox.

I have a gameing pc i have a steam accont to

I recommend CS 1.6 then.

I don't have a gaming PC.

Left 4 Dead is an old game at this point and will run fine on older machines. I mean, I picked up Human Revolution for the PS3 because there was no way in hell it would run on this computer. But I happily play older games, like Team Fortress 2.

I now have a gaming PC which I must say I enjoy very much. Has opened me to a whole new world of gaming. Member of STARS would testify that if he mentioned "PC gaming" a while back, would have barfed at the idea.

360 games: Gears of War franchise, Halo, definitely Deadly Premonition (good recommendation Yama), Darksiders, Mass Effect series (Mass Effect only available on 360 and ME2 controls are a bit crap on PC).

XBLA: Super Meat Boy, Trials HD, Deathspank.

I stopped playing L4D VS on PC because it takes so long for me to load stages that by the time I get in to the round the other survivor team has already made it halfway through the stage. No thanks, I'll stick with the relatively standardized loading times on xbox.

L4D stopped working online for me altogether, I can't even get into a multiplayer game without encountering disconnection errors. Reinstalling both L4D and Steam had no effect whatsoever so I assume it's an issue with Valve somewhere.
