Has Nintendo put out any new franchises in the last 12 years? Seems like its roughly the same games at every E3 and if this remake is the start of a trend, it literally is going to be the exact same games...
Pikmin and Animal Crossing are both from 2001, I guess technically in the 12 year cutoff but still well over a decade old. The unfortunate trend in all the other games you mentioned is that they're all for Nintendos handhelds and casual games. Still, fair enough.
I agree that they need to focus on new I.P. Sure those titles were released in the last 12 years, but how many Mario Kart titles? How many titles that feature 'Mario' in the title? They can't even seem to strike a balance even; where is F-Zero?
