Nintendo please take my money, I'm ready for next gen
If there is one thing Nintendo are the absolute masters at, its taking as much of peoples money as possible for as little work as possible.
Nintendo and the Switch are basically the reason why the whole games industry has been doing remasters, re-releases etc for the past few years. They made the industry realise that there are a lot of adults that grew up with great games and now have the disposable income to buy them again and they will do just that. Sometimes multiple times.
Nintendo released the Switch nearly 7 years ago and released:
1 new 3D mario
0 new mario karts
0 new 3D metroid games
1.5 new zelda games (perhaps being generous I'm not sure as the first one was supposed to be Wii U and the second took fricking ages and reused the world of the first...)
No new donkey kong games
1 new pikmin game
1 rubbish mario party
Despite that, its been insanely successful. They will release the new Switch once they have bled every drop of blood they think they can from the current gen and then do it all again next gen.
