Just a heads-up: you can get Saints Row the Third, Metro 2033, Darksiders (not Darksiders II), Red Faction: Armageddon, and three Company of Heroes games for as little as $6 right now. They're part of the Humble THQ Bundle
That's insanely cheap for all those games. The Humble Bundle is a "pay what you want" deal, but you have to pay more than the average to get Saints Row. If you don't want Saints Row, then you can pay as little as $1.
The sale lasts for two weeks. If you're interested in Saints Row, it would be best to grab the bundle ASAP before the average donation rises higher and you have to pay more later.
The main reason I'm mentioning this, aside from Saints Row being a great game period, is that it features a Tron-like area that should be fun to mess around in. That's part of the reason I jumped on this deal.
