How many hours should a single player game today be to warrant a sixty dollar purchase?

You poll options suck by the way, to many low hour options.

This is why I added the 21+ hour option. Remember we're trying to justify sixty dollars. If you're speaking in terms of RPG's then 21+ is the choice for you if you want robust ones like Skyrim, Fallout and Mass Effect.
