Cool, that helps a bit, if they're both the same kind of game.

But just so we're clear, you can have a 10 hour game that results from abhorrent crunch over several years. Or that is super buggy and unpolished.

Personally, I find that there is no perfect length for all games. If it's a narrative game it's easier to pace a shorter game, sometimes, and it's often easier to at least see the end, at least.

Of course you can also make a game with no ending at all. I am less and less interested in narrative games as time goes on.
