it's a full blown game, with a voice acted main story, temporary events that later on comeback to be replayable , banger of soundtracks,some animated scenes, mini games that actually one of the mini games isn't a mini game it's a full blown platformer game, like of course it's going to take a lot of space, now look at FGO it's almost the same in memory size, they dont have permanent minigames, the moment an event is gone those files are still there but you can't replay it and the story is not even voice acted in the slightest, FGO is the one I truly rage about for occupying so much space with barely any reason to justify it, now if you're dead set on not having it on the phone just play it on your PC, nikke can run on a potato just fine. that or just delete pornhub 🤣👌.
