Two things here.
1. As others have said, however long the dev thinks the game needs to be. You don't like it? Don't buy it.
2. Since when is $60 too much to spend on a game? $60 has been the standard price for a new game since 2006 and PS2 games were $50 as far back as 2000. That's amazing considering how much more expensive it is to make games. Quite frankly it's a miracle games didn't jump to $70 this gen.
Bet with Adamblaziken:
I bet that on launch the Nintendo Switch will have no built in in-game voice chat. He bets that it will. The winner gets six months of avatar control over the other user.
