So what's your ideal length for a $60 "triple a" retail game?

There is no perfect length. While I'd be okay with 5-10 hours for a cineastic game, that would be inexcusable for an RPG. For those, I'd like to have 40 hours for the main story and additional 20 hours if I feel like I want to spend more time in that world.
