Mario could be so much more alive if he talked more.
Even a simple response to a character talking to him or a small comment on something going on in the world would be nice.
That's why I really, really like Mario Sunshine. He talked (Japanese version), and there was a story. Yeah, whoa hey, Peach got kidnapped, yeah, what else is new; however, in Sunshine it was played with a bit more and taken beyond the normal "Hey, Mahdio, when you get done with your clothes and the dishes, go save Peach cuz... she just needs some saving, aight?" storyline.
It was cinematic (much to many players' chagrin... something I still don't understand). Along with Mario talking, I don't understand why people hate the idea of a cinematic Mario game. I was gonna explain more about it, but I just realized I'm tired and don't want to explain it right now (and the for the fact I've done it a million times), so I'll do it later.
