So there were a lot of cool things here, and I am looking forward to the game. That said,
omg wtf get rid of this stupid point-and-click shlt. It's boring, it's not fun, especially if all I'm doing is collecting freaking star-coins.
Also, why do we need such a fleshed out story in Mario? I hope this is the only cinema in the game, but it looks like we'll get to talk to Toads again (FUN!) and watch tons of dumb movies. The only story we need in Mario is enough to compel us to collect all the crap we need to beat Bowser; Princess is kidnapped, Bowser took her, she's in the castle - that's IT. Sunshine's failing was too much narrative, too much cohesion, not enough abstraction. Many people here said that Sunshine should have been entirely the bonus levels, and I wholeheartedly agree. When playing Super Mario Galaxy at E3, I got the impression that Nintendo was going that route, and hopefully the gameplay stays abstract even though there's some faux-justification for everything being in space now. Whatever.
That said, the game is going to be awesome. There's just so many tiny things that Nintendo gets wrong with Mario, and they've been collecting over three games.
