Lol I'm a Kingdom Hearts fan so I'm gonna give Unchained a good shot.
I was enjoying Record Keeper but it's my first gatcha game and I found some of the systems in it a bit confusing. After playing for six months I went into the OT and hadn't got a clue what most people were talking about.
I'd like to at least finish the Classic dungeons in Record Keeper but I'd love to start Mobius as well as the artwork looks gorgeous.
I've done a little reading up on the game and there seems be HD/high quality asset upgrade download or something, at least in Japan. Not sure if it's available in the global version yet. Also read that it was like a 3 gig or so download.
