This is why this is one of the best gaming sites on the net - you guys are actually promoting other platforms, just for the sake of gaming. I just signed up for Elder Scrolls Online Beta testing because of this article (I don't stand a chance of being selected). And I had no idea so many big PC titles - like WOW and Star Wars: Old Republic - were now free-to-play (to an extent).
PS - No matter how many free-to-play games there are on PC, my Xbox360 is still my gaming machine of choice.
TeamFortress 2 on Steam is loads of fun, and really puts the 360 version to shame what with the extra maps, The silly hats oh and they added a horde mode where you have to fight waves of mechanised versions of the classes.
