If we are talking specifically ones people would get mad at me for, and using the term "Nintendo Games" as any game that was released on a Nintendo console...

• The Smash series and a good portion of the characters involved's franchises. I've played some Melee and touched Ultimate once when playing with a friend but that's it - and I don't have any intention to play them unless someone wants to give me them.

• I haven't played any of the Gen 4 pokemon games specifically. Same with any of the Mystery Dungeon games barring one when I was in middle school and couldn't be damned to learn to play more than maybe one dungeon floor.

• None of the Warioware games, nor a lot of Mario spinoff games (though I have played a few of the Donkey Kong Country games as well as consider Donkey Kong 64 a great game which pisses people off LMAO. And only played the first Luigi's Mansion, never touched things like Bowser's Inside Story or others, etc etc).

• Only played the Metdroid game that was on Gamecube (and am honestly not a fan of the classic Metroidvania genre At All)

• No Fire Emblem or Xenoblade Chronicles. They don't appeal to me in general. Anything that is a turned-based RPG immediately becomes less appealing to me (yes, I even hate it in Pokemon, but it is at least simple enough for me to understand that I can finish a game). If Xenoblade Chronicles isn't a game like that then uh... whoops lol?

I have no doubt there is a bunch more those are just the ones I can think of off the top of my head. I don't really have brand loyalty beyond preferring Nintendo systems because a lot of shit gets released on them (shit that I care about, anyways) + am only a PC gamer because I get games faster/have the space for them. Even then I hate playing anything that doesn't have controller support. If other systems had more games I cared about then Nintendo, I'd use those in a heartbeat.
