Super Mario Galaxy looks like more of the same. That's not a complaint, though. New Super Mario Bros. Wii is a nice change of pace for a fun party game. Music games, shooters, racers, fighters, and mini-games have been the norm and so a multiplayer platformer would at the very least be refreshing. Why didn't they put Wario and Waluigi in place of Yellow Toad and Blue Toad? I think Waluigi needs to be in a "real" game (sports, partying, and DDR: Mario Mix don't really count).
There's also Mario & Luigi: Bowser's Inside Story and Mario Vs. Donkey Kong: Minis March On. There sure is a lot of Mario revealed this year. I love the Mario & Luigi games - playing Bowser as well this time around looks like a lot of fun - but I didn't seriously play much of the second Mario Vs. Donkey Kong and there are other games I have to catch up on so I don't know if I ever will play this new one. I used to like Lemming-type games, but not so much anymore for some reason. Now if it was more like the first, that would be good, but I guess there is enough platforming in the other Mario series.
Metroid: Other M looks good. Not to sure what to make of the gameplay. With Adam Malkovich ("Any objections, lady?") and a scene or flashback of the Mother Brain killing the (Super?) Metroid, we at least get the sense that this will cover a good deal of Samus's history. I've gotten the sense that Nintendo wrote themselves into a corner by making the Metroids extinct after Super Metroid and then again in Metroid: Fusion, especially since the series is named after them, and I've always gotten a sense that the Metroid storyline, or rather Samus's, is not as well known as it could be. At least it looks like Other M will fix all of that. (What does "Other M" mean, though? Note that it is an anagram of "Mother", and the short-form of Metroid: Zero Mission is "M0M"...) Team Ninja (whatever happened to Tecmo?) developing this shows that Nintendo is willing to work with other companies, though the choice of Team Ninja is a surprise (jiggly Zero Suit Samus?)...and what's with Retro Studios, then? Isn't Metroid (at least the main Prime series) their baby? What are they up to now - will they return to "Wiiifying" their GameCube games that Nintendo had previously cancelled? Because of those cancellations, I'm pretty sure they currently only have the Metroid Prime Trilogy to their credit...speaking of which, that's coming out too, on a single disc, with the first two now Wii-enhanced...I wouldn't pick that up, since I played them all the first time around, but I know a lot of people would.
WarioWare: DIY could be neat. I seem to have less creativity these days, though, so hopefully this won't be something I'll be be tired of after a day.
Golden Sun DS is a long time coming - I liked the first two, though not to the extent it seems that some Golden Sun fanboys seem to. It's certainly welcome, of course, though the E3 footage was minimal.
Wii Fit Plus is going to sell like hotcakes. I was thinking it was too soon to roll out a "sequel", but if I'm seeing the trailers correctly, it looks like you can set a routine and maybe they eliminated the constant-pressing-of-the-A-button issue of the first one. I've been lacking in my Wii Fit workouts lately (I just weigh myself each day, but I'm not sure what the point is when I don't have time for exercise - I'm not fat, BTW, but I'm sure I could always be a bit more fit).
Wii MotionPlus with Wii Sports: Resort - guaranteed mega-sales. Hope the MotionPlus is supported by many games. Wii Vitality Sensor - what is the point of that? Did I miss something? I didn't see any game making use of that, or am I mistaken? Well, if Nintendo can make a game based on sitting, standing, or breathing (Wii Fit), I supposed you'd expect that they'd be able to make a game around sleeping, or just having a pulse. Only Nintendo, right?
Anyway, there's lots of Mario this year. And a few other things. I don't think anyone who complained about last year's Wii Music and Shaun White Snowboarding should be complaining this year.
