Quote from Charlie Brown
It's his game, his plans, his choice. Next time you play a beta version of a game don't get your expectations running that fast. Whether the game is ruined or not depends on the person who is judging it. From all I heard, it's isn't that much of an ending, but still it doesn't really do harm to the game, as you can 1- avoid it, and 2- continue after it.
....then why have one? If you have no incentive to go towards an end that exists, and you can continue playing as if nothing happened after said "end", then it's *not and ending* and serves absolutely no purpose. And no, a developer going back on precedent and concepts that he's already established isn't subjective and a "to each his own" thing. Notch set minecraft up with a much longer history of being an open ended sandbox than any sort of objective RPG with story elements. It doesn't matter what he's said, because what he's *done* is made a game that's an open sandbox that's in a contained universe with no story or characters, and thrown in RPG elements and an "end" and what is proportionally the last minute. That's got nothing to do with opinion, that's what he's done. So once again, why throw in an ending that doesn't serve the purpose of an ending?
