Pokemon fans were so desperate for any kind of innovation instead of the same game over and over and over with worse pokemon designs. At this point the ai ripoffs feel more like pokemon than actual pokemon. An ice cream cone? Ice cube head penguin? Really gamefreak?
It is crazy. Not to mention all of the other attempts at the Pokémon "formula" have mostly just rehashed it. Cassette Beasts is the first I saw that really made some changes... And even they were slight. Digimon and Shin Megami Tensei are quite different but they've also been around for yonks.
