Oh my godddddd she's perfect!

It depends on the game. The Cinderella Girls and Million Live games are rhythm games like DDR. Gakuen is a sort of deckbuilding mechanic. Plus of course the usual gacha stuff around collecting outfits and levelling up your idols, etc

iM@S also isn't localized so you'll be playing in raw Japanese. Honestly no I don't recommend the games unless you're really into it. If you like any particular girls you're best off just watching their "commus" on YouTube or bilibili or whatever
