for nintendo consoles, nintendo creates it userbase.
thats being obvious from nintendo 64 days most of big games were nintendo.
with the exception of random rare games.
and it's the same for the wii, third party went HD, and nintendo it's pushing more casual games because they are cheaper to make and are selling more, plus they already released many of it core games, except a full wii zelda.
more of the wii userbase it's casual probably.
while this is true, for most of third party i don't see how it affect marvelous their games are niche.
of course they won't sell.
