User blog comment:Dorayaki/The Fallen Stars? --- What have been occured to Aikatsu Stars!/@comment-31567220-20180202110411/@comment-3487190-20180204135842

We might expect Stars series to go longer so that it can fully ultilize the settings inside this series, but anyway, I think two years are overall enough to tell the stories for just Yume and her pals.

The critical thing is that the shortage of arcade content also makes the characters not able to have further achievement in the anime story. In the old time of origial series, the dresses and appeals are kinda like the ability or reward for idols, the more dresses and appeals you show, the stronger you're. in Stars series. the idols are portrayed to be strong and popular but you cannot see any difference in them as nothing changes in the CG live.

Pripara series, on the other hand, we can at least see Yui and her friends get newer cylume dresses with the story..
