Minigame Surplus?

Honestly, what is up with all of the mini-game games on the Wii? Plus, why are they all the exact same thing? I know, the third party hasn't liked Nintendo since the Nintendo 64, but, don't you think they would want to give them a second chance? It is these things that scare away the hardcore gamers to the Xbox360 and PS3. I mean, the 360 and the PS3 have better visual capabilities and a larger capacity, but that is really no excuse to diss the Wii. One of the only reasons Nintendo is still classified as a hardcore/family company is due to the first and second party. However, there are still games like Final Fantasy and Residient Evil that help out the cause. However, the 3rd party should not be scared or anything. I'm just saying that if the 3rd party acted like the 1st party by producing more hardcore games and such.
