ohhh boy.
If we want to do list wars, just looking at my shelf, Mirror's Edge, Tales of Vesperia, Valkyria Chronicles, LittleBigPlanet are all games with unique visual style or interesting takes on their genres. Then of course you have games like Braid, Flower, Fl0w, and PixelJunk Eden. I wouldn't use the ratio argument as that's the same stupid argument people use against Wii regarding quality to crap. Ratio doesn't matter to me. I can wade through the shit to get to the gems.
If there's one thing that annoys me, it's innovation for innovation's sake. A game that's just different to be different is boring to me. I want a game that does something different for a purpose.
As for DS, the system is amazing but I don't think Atlus doing great things with it helps you point as they haven't really done anything on Wii aside from Trauma Center which is an extension of a DS experience (and something they killed by stupidly launching it a week after Mario Galaxy).
Edit: I said artyle style because you listed Muramasa which is only notable due to its art. And then you said 2D Dot Heroes which looks to be an exact clone of Zelda but with stylized graphics. You seem to care about visuals more than you yourself realize.
