Adventure Time: Explore The Dungeon Because I DONT KNOW! seemed like it was gonna be awesome. All the signs pointed to it being great. It was gonna be a 4 player dungeon crawler. Way forward was making it, and they made the previous game, Hey Ice King Why'D You Steal Our Garbage?!?!?, which was freaking amazing. Then I bought the collector's edition, which was 50 bucks. It sucked soooo badly. The dungeons were extremely repeitive, the 3ds version didn't get multiplayer, the story wasn't entertaining (plus Pennleton Ward said there was a huge story reveal about Princess Bubblegum that was gonna change the show big time, and the only thing it revealed was her age and her parents) and the enemies were extremely bland. I went the next week to trade it in, and it already had such bad reviews that I only got 2 dollars for it.
I heard the new Adventure Time game that came out was pretty good, like the first one, but at this point I'm too afraid to try it
