I've seen 3rd party games that have deserved more sales... though i haven't seen games that would sell more on another system even if the graphics were bumped up.

Games you would expect to sell better is a better way to say it. 

I'd say Zack and Wiki deserved to sell more than it did, but it doesn't follow that it would have sold ore had it not been on the Wii, which is the contention here.

You seem to me making the case that a tradtional game is a hardcore game? I disagree with this if 

that is the case. 

I actually don't consider platformers to be "hardcore" games in the slightest - the controls (certainly for 2D platformers, such as those on the DS) are simple (up, down, left, right, jump) and anyone can pick one up, play it and enjoy it. Yes, there are hardcore platformers no doubt (although I cannot think of one off the top of my head) but the fact that my other half who ignores gaming totally was able to pick up the DS and play Super Mario Bros on my DS without my input or reading the manual supports this in my view.

As for Super Mario Galaxy and Twilight Princess - both are established, respected amd highly hyped brands that appealed to Nintendo fans - hence all those went out to buy them, plus both feature bright colourful, cartoon like characters/graphics hence appeal to the casual market more than gritty, adult, blood and guts FPS's. 

Oh, another amusing thought is you have both this and Crazyman's thread.

Apparently Mario Galaxy is proof that both only gamecube owners have bought the wii AND proof that only casuals have bought the wii... despite gamecube owners pretty much being the definition of non casual.

Since they didn't market the game at all, I'm not really sure it deserved more sales than it got. Internet-savvy gamers have heard about the game a lot, but most people haven't, and what they see at the store is a kiddy-looking game cover which doesn't say much about the game.

Zack & Wiki potentially deserved more sales than it got, but Capcom didn't fully explore this potential.

Press the Button go and play the original Ninja Gaiden that games was hard and not just anybody could play that. Most games today are way too easy because they try to do overly complicated things and hold your hand through the entire game. Console FPS comes to mind. In fact I think that is the reason that online play is so much more fun today because ti reintroduces a measure of skill. I haven't seen a game that I can't beat in a less than 3 days in a long time.

Exactly. The game itself deserved advertising, and thus higher sales. It didn't deserve low sales just because its corporate parent decided not to push it.

That is the big deal. Which one of these games would do better on the HD consoles? The opposite is also a valid question. How would some PS360 games do if released on the Wii? I dare say some games would have sold more on the Wii.

My bullshit o meter goes crazy when I hear that the Wii is too casual for these games. Look at the Orange Box sales. Where are the uber harcorez? Maybe it is Valve fault for releasing a game that is not fresh or offer enough new content to please the hardcore crowd. Guitar Hero 3 is the opposite of the Orange Box , original, hardcore centered and full of new ideas.

OK, let's rephrase my original point as "no 3rd party company deserved to sell more games on the Wii than it sold". That's the key thing as long as we're talking about gaming as a business.

And also, have these Japanese devs ever heard of a hardcore Wii game called No More Heroes?
