To the op, your first post leaves something to be desired. Maybe a more specific question or more of your own opinion. Anyway here is what i thought.
Although the title is bowser's inside story i didn't expect to play as bowser as much as i did. The story is a little odd but normal considering its a mario game. The combat system is fun but once you learn how to get a perfect hit every time it gets repetitive. Being bowser is really fun since i'm used to be the small guy in the other mario rpg games. Mario and luigi don't get much of a role in the story until you figure out how to get them out of bowser which could be a few hours into the game. I haven't finsished it yet but overall it is worth buying.
