To be honest "Open world RPG's" like Oblivion and Fallout 3 killed the JRPG fanbase in the US. People now Expect that kind of gameplay when they hear the words RPG. which means they get upset by small hallways when playing. Nevermind the fact that even though they can get 150 hours of play time running all over the world in one of these sand boxes theres only actually about 5 hours of actual story available.

Even games like Mass Effect and Mass Effect 2 have very little story if all you do is bum rush the story mode.
