Definitely listen to munkeh's advice, especially when it comes to newer games on Steam, but for now you can't go wrong with many of the Valve classics like the Half-life series, and I highly recommend Torchlight 2. It's not exactly a graphical powerhouse, but it's a highly addicting Diablo-style lootfest at under $20. Will keep you buys for weeks if not months, and before you know it those amazing Steam sales will be here.
Oh, and Team Fortress 2 is an amazing multiplayer game. And it's FREE!.

You know I was always wondering why no one ever used the dollar sign for $ony, but then I realized they have no money so it would be pointless.
