I've had all the Nintendo consoles save the GC (I fed up with consoles with PS2 and I became a PC gamer), and it's always the same...
The "problem" is Nintendo makes awesome games, and 3rd parties can't even smell that quality many times... it's just that...
Is there a better "racing game" in Wii than Mario Kart? Nope
Is there a better fighting game in Wii than SSB:Brawl? Nope
Is there a better 2D platformer in Wii than NSMB:Wii? Nope
Is there a better 3D platformer in Wii than SM Galaxy? Nope
Is there a better adventure game in Wii than Z:TP? Nope
Is there a better "shooter" (well, actually is not a usual shooter) in Wii than MP3? Nope
...
...
And so on...
Why I should buy a shooter like Darkside chronicles and Dead Space when I already have HotD:Overkill? Maybe these two games are better than Overkill, but I won't pay 50€ for yet another shooter... Hell, if they released a decent RE or Dead Space, and not dumbed-down-different-genre-spin-offs I would buy them.
The conduit bombed... ok... it is just a generic game... We, Wii users are not graphic whores (for that we have the HD twins)... so please, just do a good and fun game to play... I don't mind it has so "good graphics for the Wii". It is incredibly generic...
Madworld "bombed" (well, that's what some people say, I think it was a success)... It's awfully niche and low cost game. I have it, but of all the people I know it only appeals to a few.
Muramasa "bombed"... Another niche game... I love it, but it is still niche, and is REALLY hard to find in stores... I am Spanish and I bought it in Finland, because in Spain I couldn't find it.
A boy and his blob "bombed"... I really want to buy this game... but I didn't know when it was released due to the ZERO press and advertising it got. And until now I haven't been able to find it in Spain... Just in Amazon UK
As a "hardcore player" and Wii user I am really annoyed this gen with many of the 3rd parties... We get the crappiest games and with less effort of the great majority of them, being only some small studies the ones that really take some risk or effort to make good games. For getting a SH:Shattered Memories we get tons of crappy spin offs and dumbed down franchises, along with horzez and all the like. Here in Spain you could see a lot of "exercise games" and party games ads everywhere, but any good single "traditional" game... Then, what did you really expect to happen?
PS: Not that the other consoles don't have problems though... I read EDGE every month and the majority of the HD twins games look all the same to me... and when a really good and innovative game is realeased (like bayonetta) it also flops... 360's top ten is just horrible, 9/10 being shooters... I don't know, maybe I am just tired of some kinds of games, but yuk...
