What Mario game do you think has the best storyline?

Even for a Mario game. *finishes sentence like stereotypical twin*
 
Ah, but I put a period, take that!! >:-)
 
Luigi's Mansion's storyline was great for this particular reason: it does not involve Peach getting kidnapped, and Mario gets stuck in a painting. Even though Luigi is a gullible fool in that game, and King Boo even comments on that.
 
Too bad "Bowser" is the last boss, though.
 
Actually, King Boo is, but I don't mind Bowser being the main antagonist. I mind how broad his scope of schemes are though.
 
But really, not many people play the Mario platformers for the story anyway.
 
I know that, but some critics lower the score for Mario platformers just because the story sucked. I usually care about gameplay over story. If I want a good story, I'd read a book instead of watching 15 minute cutscenes.
 
Probably not, but Bowser just sounds odd, though, IMO.
 
I thought Bowser's voice was fine. It was nice to see him talk for once. I really didn't care how corny it sounded; I appreciated that a Mario game had full voice acting for once.
