Do you know what I bought a PS2 for? Fire Pro Wrestling Returns. My brother bought it for Disgaea. A friend of mine bought a PS1 for Skull Monkeys of all things. That's how it all works. But Nintendo just assumes that they have Mario so everyone will flock to it. So much so that they'll go with two Mario games, two years in a row and then follow that up with a game that plays almost exactly like Mario. An increasingly homogenus lineup from Nintendo with no third party support is just going to appeal to an increasingly narrower audience. They need variety to win different people and different demographics over but instead they're squeezing out franchises like F-Zero, Star Fox or Metroid. They fail to see the value of games like that.
Pikmin 3
The Wonderful 101
Bayonetta 2
X
SMT X Fire Emblem
Hyrule Warriors
Oh yes, nothing but platformers aimed at Mario fans.
Only two of which were actually made by Nintendo (Pikmin 3 & X), and only TWO of which have even been
released yet (Pikmin 3 & Wonderful 101). And of the ones that
haven't released, 1 has only been shown off using concept art
from other games (SMT X Fire Emblem) so it's pretty much vaporware by now. 1 more looks like **** (Hyrule Warriors).
It's also worth noting that the games on this list pretty much sum up the Wii U's entire announced software lineup for the rest of its lifespan. That's some variety, especially when half of the games on this list use the same bright, cartoony art style (nothing against the art style, but when every game on the Wii U has the same look it gets old).
