First up, we have FlingSmash(nee Span Smasher), the retail MotionPlus-powered Breakout-y adventure which received steaming heaps of glowing impressions at the last E3. I'm really excited about this game, even though it's dev'd by Artoon. This is the kind of colorful, wacky shit that fuels my madness.
WarioWare DIY on the DS has an insane amount of potential. Create your own mini-games, complete with music, graphics, and AI, and trade them online (or play them on your Wii)? Hell. Yes. I hope the creation tools are intuitive and super-flexible.
Speaking of playing them on your Wii, I initially thought that the WiiWare Wario...Ware was just a conduit to play your DIY games on the telly. It seemed like a bit of a cash grab, but reading the press release more closely, it's apparently a lot more than that. Bonus. * Launching on March 29, WarioWare: D.I.Y. Showcase is a standalone product exclusive to the WiiWare service and available only from the Wii Shop Channel. The game contains more than 70 new microgames and features interoperability with the WarioWare: D.I.Y. game for the Nintendo DS family of products. Players that own both games can transfer content between the two via a local wireless connection, and can even play user-created microgames on their television using WarioWare: D.I.Y. Showcase.
The long, long wait for Picross 3D is almost at an end. Looks like a neat spin on an already brilliant concept. Perfect for whiling away the hours of your portable day.
X-Scape is a terribly named but nevertheless intriguing DSiWare mix of the traditional and the avant garde from Q-Games, the Trajectile/Pixeljunk guys.
Metal Torrent is a sweet-looking downloadable bullet hell shmup that looks to push the DSi to its limits.
Then there's the hilarious Photo Dojo on DSiWare, which demands purchase, regardless of its actual quality.
Art Style: Light Trax seemed like it would be a port of DotStream, the minimalist Bit Generations racer, but it has definitely undergone a funky facelift during its trip to WiiWare.
Art Style: Rotozoa came out of nowhere (and ended up on WiiWare). I don't know how fun it'll be, but the aesthetics are amazing.
I think this list proves that Nintendo is offering plenty for the true hardcore - the crazy niche gamers like me who demand that their games OOZE quirk and style and Japanese flavor (even if they weren't developed there).
Combined with powerhouses like Mario and Metroid and quality boutique games like Sin & Punishment 2, I think a pretty solid case can be made for Nintendo's front half. And that's just first/second-party! Combine that with a hugely-enhanced, value-added version of Monster Hunter Tri and Dragon Quest IX, with a Nintendo-published push, as well as all of the other third-party offerings, and your wallet will be crying for mercy.
