With Mario and Donkey Kong I only liked certain titles. The Marios I like and would own are the original, 3, super mario world and 64. With Donkey Kong I only liked 64 and the country games.
I also loved Wario on gameboy. =D
Pokemon still is tbh. I got that Omega Ruby one since it had been some years, still basic set up but it did have interesting moments like "oh yeah there are many parallel worlds. one without megaevolution (aka original titles)" .
