Show me Resistance. Lots of art. Lots of atmosphere.
Well, obviously no Wii game will have textures as high-res as PS3 game, but Red Steel looks like "lots of art, lots of atmosphere." The Call of Duty series has always been notable for its atmosphere, and I doubt the Wii iteration Far Cry will be any less atmospheric than its predecessors. Splinter Cell is a port, but it does mean that Ubisoft is planning to support Wii with its mainstay "serious" franchises.
Lots of challenge. Lots of narrative.
Twilight Princess. Disaster: Day of Crisis. Square-Enix support.
I'm a seasoned gamer and I'm accustomed to getting more more more.
The next iterations of Zelda, Mario, Smash Bros and Battalion Wars look like they will up the ante over their predecessors in every way.
Meanhile Nintendo is touting less less less.
Wrong. Nintendo is touting more and more
diversity. That means more games for serious gamers. More games for casual gamers. And more games for non-traditional gamers. You are focusing only on the games not targeted to you (and I'm still waiting for what you think about the existence Hotshots Golf, which directly competes with Pangya--is Sony leaving you behind by supporting this franchise). Like you, I'm completely uninterested in Wii Sports and Pangya...but I'm rational enough to ignore the titles that aren't targeted toward my demographic.
You just don't seem able to wrap your mind around a diverse library. Just like people who think Gamecube is just Mario games and Xbox is just FPS's, you think Wii is just arcade sports. Wii is launching with the largest and most diverse library of any console ever, and you can't focus on more than 3 or 4 games. If anything, Nintendo is in danger of over-saturating the market at launch rather than focusing too narrowly on one kind of gamer.
