 Agreed. Do the new Advance Wars.

An older one but Project Slypheed.
Great game, fantastic art design and I have never met anybody else that has even played it.

 Late night posting FTL...haha! Cool points in the negatives, now.

games that i personally love and think the masses have overlooked.

no more heroes - wii
puzzle quest - various platforms (i have ds version and love it)
trauma center - wii/ds
beautiful katamari

that's all i can think of at the moment. i'll check back in later if i think of more.

Six Games You Should Do (in no real order):
1. Viewtiful Joe (GC,PS2)- Didn't sell that well, but it was an awesome game. I'm still looking for Viewtiful Joe 2.
2. Batallion Wars (GC)- This game had some flaws (like no multiplayer), but it was still a very good game, kind of like a real time Advance Wars (which is another one you should do, that game was kick ass). Batallion Wars 2 also should sell better, but I haven't gotten to play much of it. Do a joint review of these.
3. Earthbound (SNES)- This was an excellent RPG that did not sell very well in America. It stars Ness, who most people only know as that black-haired kid in Super Smash Brothers. It would be nice if Nintendo made a new Mother game, or at least localized Mother 3, maybe in an expanded DS release.
4. Chrono Trigger (SNES)- my all-time favorite RPG, this sold less than 300,000 copies in America. More people must play this game. Chrono Cross (PS) also didn't sell that great here, that would be a good one to do as well. It would be awesome if they made a new entry in the series. Please stop remaking Final Fantasy, Square, and release a new Chrono game.
5. The Metroid series (many)- This is a great series with some of the greatest games ever that does not sell very well. It would be great to publicize the Prime series especially, since 3 came out just a few months ago.
6. F-Zero series (many)- This is one of the few racing series that I like. These games also are so hard that they could make you cry (especially GX's story mode). Maybe time this for when Nintendo inevitably announces F-Zero for Wii.
I also considered Secret of Mana, but after Seiken Densetsu 3, this series REALLY went down the crapper. If they somehow come out with a new one that is even close to as good as Secret of Mana, review it.

Hmmm ... maybe Crush would be a great start :)
