This game is really good - the beatmaps are fun, models are nice, and the songlist is great. However, it is fairly different from the chinese version (Diva Destiny).
The highprofile voice actors in the Chinese vers (like Maaya Uchida for Chloe) have been replaced with lower budget ones - I assume this is so they can have character songs that are actually sung by the characters, or some licensing issues. As well, the song list is vastly different, but (imo) usually the JP vers is better than the CN vers. (most seem to disagree with me tho! lol) Also there's paid-only songs which is kind of shitty...idk if that's in the CN version.
Honestly, if you can't read either version (or can read both), I'd try both Memories of Link and Diva Destiny, and see which one you like more! They're both pretty high quality. Personally I'm gonna stick with the JP vers despite the drawbacks just because I can read it a lot better lol
The graphics is smooth and high quality, music library is pretty good I liked some of them, personally the voice acting feels really odd to me for some reason. I couldn't really find myself playing too much of this game unfortunately probably cuz I'm not that interested in the characters themselves, they are like pretty dolls with a weak personality. There are many other music games like this which are just way better.
this game is amazing, im planning to get a phone with more memory (i got only 16gb and 10 is used by phone system) and olso because this game and bang dream takes a lot of battery so i need a powerfull phone . exept for this i love this game so much more than the other rhythm games and i really hope we get to have this in english too
