Have you finished Lego Dimensions yet? Something spectacular happens during the credits which, coupled with a revelation in the final boss battle, makes the game 100% worthwhile.

The end credits made me laugh my butt off. 

The game is full of wit.  I keep saying this, but people avoiding Lego Dimensions and Disney Infinity 3.0 are missing out on two of the FUNNEST games in recent memory. I love me some grim dark games, too, but these two games really brought the sheer fun back to gaming.
