I get the people that are saying Walmart, they don't have a ton of game deals (although their Black Friday was more than solid), but they aren't really primarily a game retailer, so I don't mind. They are just sort of neutral in my mind.
On the other hand, games is all Gamestop does, and I think they do a pretty terrible job at it. Their "new" (for some value of 'new') game prices are pretty terrible - which is almost primarily what I buy, I like my games to be in good condition - and on top of that, I actively dread going in the store. I don't want to be bothered about pre-orders, rewards points, etc. Their business model just bums me out, I guess.
So what I'm trying to say is I nominate Gamestop =)
