Fate Grand Order for me. I want to be able to decide when events are held, stuff like that. Not when the developer decides. A lot of these games have interesting ideas, but unfortunately are stuck in a "gatcha" format.
Honestly it gets so much right... but it's a gatcha game with terrible rates... all I could think when I was playing is why can't this just be a game, that I buy and its done. The characters are interesting as are the dragons themselves.
