I can count on one hand the number of games for which I've paid full price. The last one was Mass Effect. The next one will be Brutal Legend.
I generally buy games used, so my gaming dollar goes to glorified pawn shops and random Amazon sellers. The developer never sees one cent (I've got a mortgage, dammit. Don't judge me!). However, I want Double Fine to take my money for this game. This type of creative risk should be encouraged.
