I'm not sure I'd pay $50 for a game unless it's one I REALLY wanted because friends were playing. I buy a medium amount of games but they are almost all are $20 and under. I tend to not like the big AAA production type of games except for a few exceptions (Mass effect, Uncharted, Skyrim but that's about all) but I love super meat boy, spelunky, bastion, banner saga, and tons of other indie games like them. To me it seems a better business model pay a smaller price from a digital delivery platform (Steam, iOS app store, google play store etc...) that a much larger chunk goes to the actual devs.
