This isn't by mojang lol. It's by Double Eleven. Sure their name is on it, but I'm betting that Mojang didn't do much.
Lol I had no idea, thanks.
If somebody only get a few hours out of this game then they aren't playing it very much like it was intended to play as a dungeon crawler loot RPG. I got a few hours out of it just during the PC beta, so I am quite confident that doing the gameplay loop and leveling up to play through the harder difficulty runs and to find some of the secret levels and such will be plenty of play time.
That's fair, I love a good loot grind.
