In some way you do make a lot of sense. Me and my sister did tak this ont once adnd we had the same opinions. Pretty much Pretty Rhythm came out before Aikatsu, being one of the first few collecting idol arcade games ever. Aikatsu did come out next, with its own fresh theme and ideas, that were similar to it in a way. I've seen alot of people say that Aikatsu is copying Pretty Rhythm and I do kinda agree, since the idea of appeals was kinda taken from jumps. They dont have the same method though.

Pretty Rhythm didnt stoop down to Aikatsu's level and didnt change their theme at all. But as Pretty Rhythm ended, PriPara decided to go down to Aikatsu level of idoling, with basic students as idols stuff, with the story of them juggling nomal life and Idol life. Basically the Idol slice of Life

Which is funny, because Aikatsu Starts seems to have tried to copy Pretty Rhythm and PriPara, ans Aikatsu Stars now has a mild DARK theme (the evil principal) and tries to give the anime a bigger and more complicated story, instead of just them trying to be better idols everyday. AS! Also copied tha whole idol romace themes, from petty much amost every idol anime ever, ecause its a thing that fans love from PR and PP, the Aikatsu lacked.

But IDK this is my opinion
