Raising the bar in terms of game design and quality of licensed games. Game length isn't the only bar out there, no matter how much you seem to think it is.
Not the only, but it is a sore spot. I can see where you're coming from, I'd rather pay 3 bucks for a small container of JIF peanut butter than 2 bucks for a pound of "Store brand" for obvious reasons. It's just distressing to hear that a very anticipated title might be skimping on the game content, especially when what we've seen of it is very cutscene heavy, though that's not necessarily indicative of the entire game.
Most of the Elder Scrolls series, to me. Haven't played Skyrim (mostly because of how much I failed to enjoy the other games in the series), but the rest of them were a chore to try to slog through.
Did you play any of Saint's Row (especially 2), any of the GTA games since 3, Red Dead Redemption, Fallout 3 or New Vegas, Just Cause 2, LA Noire, the Mass Effect series or Borderlands 1/2?
Let's not act like 12 hours to clear Link to the Past is anywhere near a speed run. If that doesn't do it for you, then how about other games like the Portal series, any adventure game, any other game in the Zelda series. Or the Mario and Luigi RPG series, which Stick of Truth is largely similar (in gameplay) to.
I think the major disconnect here is, aside from Portal (where let's face it, Portal 1 was kinda short, but it was indie so it was forgivable) is that you're comparing to old school console games.
