Rift has a great deal with Raptr.
So hear it is, You go and instal Raptr (I've been using it for a few months now) This logs your time in games, and tracks achievements. Think Steam for example. Anyways, after 16 hours of play or so, with Rift lite, they give you a free copy of the game.

I've already got one copy, created another Raptr account, and am working on the second. Great idea for those of us who want to Multibox Rift, but haven't got into it too far yet.
