I don't see how the presence of a single, lone character from another game not made by Playtonic can make people this upset. He probably won't take up that much screentime, heck you probably don't even HAVE to interact with him; the game is designed so that you don't have to collect all the Pagies or go for 100% completion beat the game, you can easily never have to interact with him. But no, it seems for some people, his mere existence within this game somehow "ruins" it, and no longer makes it a 10/10 game.
I seriously can't believe someone genuinely, unironically said that on these forums. X(
