I think a lot of gamers, specially AAA gamers, probably associate "free game" with "crap game"... why else would it be free? 
Probably the hardest is to find the right balance in the price, so it doesn't come off at "cheap crap" but doesn't come out as over priced either. Cause if you set it too high, you'd probably have it hard to sell (they would rather give money for that "sure" AAA game) and the ones that pay the asking high price would probably complain that it's bellow their expected quality...
