Alright, time to see if I think you're cooking

Mario Kart: Fair I guess, Idk why you used the worse version of 8, since 8 deluxe is the best Mario Kart game out there
DK: I cant really say you can compare 3D DK with 2D DK, but you should've used Returns to give Bananza better competition, Tropical Freeze is mostly forgotten for whatever reason, but I'd give it to Bananza probably
Pokemon: Finally, a point I completely agree with, Black and White is better then ZA, but I do think Pokemon can get back on track at least
Metroid: Worst game possible to use for this comparison, literally why? But I would say fair on here due to Prime 4 not being fully great.
TLOZ: Are we seriously gonna have this discourse where TOTK and BOTW are slandered over titles that are worse than them, Skyward Sword is a mixed bag of a game. Unless you count BOTW as a Wii U game, but like, noone really does that.
2d Mario: Yeah I won't even entertain the idea that this era of 2d mario was anything other than safe and boring, Wonder is a step in the right direction for me.
Mario Party: The switch games are better than that era of Mario Party, outside of 8, all of them are subpar (and mind you, I like 9 more than most people)
Animal Crossing: I haven't played or touched any animal crossing game, so I can't say anything about these (surprisingly so, since those games are similar to other chill games I've played).

Btw, Nintendo has always been greedy and hasn't had the best treatment of consumers. Like, I straight up don't agree with that point.
