Five games have gone Free to Play on steam today. Champions Online, Global Agenda, Spiral Knights, Forsaken World and Alliance of Valiant Arms have been added. As a limited user, some features wont be available. I have no idea what features these are since I’ve never played any of them, but you’re playing for free, so no whining! In-game stores will still be available though, and you can use your steam wallet to buy stuff. Hopefully, depending on how successful this is (see League of Legends if you doubt it can be successful), this trend continues with future MMOs.
