From now until October 10th at 10am PT, you can get your gaming mitts on as many demos from upcoming games on Steam as you can.  Or maybe "as you want" is more accurate, since technically if you forgo sleeping, eating, and general hygiene, you can probably play a ton (but at what cost?)

Speaking of cost, though, it's worth repeating that these are all FREE. Just make sure you wishlist your favorites to be notified when the game officially launches on Steam.

More cool stuff:
