DragonQuest VII on 3DS. I don't mind a long JRPG, but this one just had way too much filler. The game just hands you busywork, along with long pointless cutscenes that don't even look cool. You know that cutscene that plays in Ocarina of Time when you open a chest? Imagine something like that playing everytime you open a door, change classes, get in your airship, etc.
The game has a nasty way of making you take the longest possible time to do anything. There's one dungeon where you are forced to walk through it five times. FIVE TIMES! just to get back to the village elder and talk to him.
I'm not kidding here. DQVII could have been a 60 hour JRPG if they cut the pointless fat out of the game. It takes thirty minutes to even see the end credits after you beat the final boss, because you still have to go around talking to all the characters you met over the journey.
