Best Buy or Target, 5 games for $30 in one package.
Besides, you can buy Garry's Mod online for it once you have installed the games and start using at least one of them. If you don't know what Garry's mod is, get with it and look it up. I *know* you're a modder. You can play all sorts of funny little games with stuff, check out people's downloads (Virus check/defenses *up*!)
Create pictures, make comics. Go crazy. Knock yourself out.
Seriously, you won't regret it. DO EET! DO EET NAO!
That's right, Bixby Snyder folks.
