1st gen: Recognize all of them and can name the vast majority of them
2nd gen: Recognize most of them and can name some of them
3rd gen: Recognize a handful and can name maybe 1 or 2
4th gen and onwards: Here Be (Pocket) Monsters
Watched the anime, probably dropped out during/after season 2 (The Orange Islands) and the first 3 movies.
Collected the cards cuz I liked the art, but never actually learned to play the damn game.
And this one might be more controversial: Have never actually seriously played/beat any of the mainline games, but have for some of the weird spinoffs like Pokemon Snap/Pokemon Channel/etc.
Fourth Gen is easy because half are evolutions of old mons
