Hmm, I certainly agree with you about the silly little mini-games going wild on the Wii. I think the DS is suffering from that as well. Nintendo kind of disappoints me with this, because their system can do so much more. I would have never bought a DS based on the game library out there, the reason I bought it is because I saw what all it could do with homebrew and how easily and cheap it was to get an R4 in order to run homebrew on it. Now I use the thing for a movie player when I travel, and ebook reader, I use it to play my old classic adventure games via SCUMMVM, I use it to play my SNES and NES and GB games via emulator. It really is a brilliant little device, but to be honest, I wouldn't care a thing about it if it were not for the homebrew. All the games for it I have seen, save for a few, are all those silly mini-game sort of things. It needs more Metroid Prime Hunters and Phantom Hourglasses. It is able to handle these great games perfectly well, why not make more of them?
I can see where guys like bkev might find the Wii gimmicky, but I feel that it is just another step in video game evolution that Nintendo, like usual, is pioneering. A Blu-ray player on PS3, how is that not a gimmick aimed at selling consoles?
