you can mark one more for the 'anti-rent' mentality. if i'm going to pay for something, i'm gonna want to keep it, not give it back. i'm not keen on throwing money away for nothing.
Truth be told, I'd rather do the same. Then again, there are some games that I just don't want to bother keeping. One thing that comes immediately to mind is Braid. It was all right for a game but now it will just rot in my Steam library after I played through it once.
Also, consider the EC episode linked above. They did mention a really awesome idea, in my opinion. It goes like this - the money you've spent renting a game, go towards buying the full thing. So if you've paid, say $20 in rents and the game costs $30 total, you can just pay the other 10 bucks and buy it.
