New Super Mario Bros. Wii - I can't find anything to dislike here. A new Mario 2D platformer? On the Wii? Awesome! The co-op stuff sounds interesting as well.
Wii Fit Plus - Yeah I'll pass.
Mario & Luigi: Bowser's Inside Story - Crap, more awesome Mario games? Following on the heels of Superstar Saga (which I enjoyed but not enough to complete) and Partners in Time (which I loved), this one apparently takes place, uh, inside Bowser? I saw some videos for the Japanese version of this a while back and it looked pretty great (you also get to play as Bowser), so I'm excited.
WarioWare DIY - I never really got into the WarioWare games, and this sounds mostly like more of the same but with the added 'make your own' aspect, which could be cool I guess. I'm sure it'll be fun (the series is a pretty big seller for Nintendo) but I can't really make myself care.
Golden Sun DS - While I'm not generally an RPG fan, I did play a decent amount of the original Golden Sun (on GBA) and it was enjoyable until I just gave up. I'm glad to see they're revisiting the franchise, but I doubt I'll pick it up. RPGs scare me.
Mario vs. Donkey Kong: The Minis March Again - This is actually MvDK 3, with the first one being a kind of obscure GBA game that was a sort of puzzle solving platformer and the second one being very akin to lemmings. I loved the first, and enjoyed the second but found myself getting bored after playing it for a while. This is also on DSiWare, which is intriguing. I don't have a DSi either, so I guess even if I was super enthused about it I would still need to pick up a new DS (again).
DSi Facebook Integration - I'm sure this would be cool if I used Facebook more than I do (which is barely at all).
COP: The Recruit - I don't know much about this except it's a third person action game for DS kind of like GTA. Who knows? It could be cool I guess.
Kingdom Hearts 358/2 Days - Hey, I don't care! What does the name mean though? Kingdom Hearts 179 Days? Oh well.
Wii Sports Resort - I want to say I don't care, but it might actually be kind of cool. At least for parties and stuff? No? Well screw you.
Wii Vitality Sensor - Uh, what? Pulse monitor? This is where I almost started to lose faith in Nintendo. I am not ashamed to admit that.
Super Mario Galaxy 2 - Awwwww yeah. I loved the shit out of Mario Galaxy, and this looks like more of the same awesome (hopefully with less swimming). I will confess that I switched browsers during this part so when I started watching again I missed that it was SMG2 and I kept wondering why they were showing clips from the first game. It's similar, though that's not a bad thing.
Metroid: Other M - This was a pretty good way to end the conference. Brawler-style Metroid game (with 3rd and 1st person stuff) made by Team Ninja? Pretty awesome. I still need to play a Ninja Gaiden game, but I'm pretty excited for this just because those games are so popular. Hopefully it'll be awesome!
