can someone post virus-free stand alone games?

Echo did a great job of posting Fallout 3 and its DLC (still having a blast playing it). However, I have been really wanting to play COD Modern Warfare 2, Battlefield Bad Company 2, and GTA IV: Gay Tony, but there's a problem: I'm a poor college and a cheap bastard who doesn't not want to fill the pockets of greedy CEO's who rip off the fanboys who will pay the ridculous prices of new games.

So, can someone please post as many of these other free games as possible to the site. Thanks in advance to Echo or anyone else who does this.
