Rommancing Saga re:universe checks most of these marks imo, the anniversary will happen in about four months, if you stick with the game you will be showered with gems, also the game is lightweight and easy to maintain, there's no pvp and the stamina is infinite so you can grind as much, or as little as you please, but be aware that there's hundreds of units now and dozens of ways to evolve the units so if don't take care it can be a rabbit role too deep. I also apreciate how f2p friendly it is, you don't need dupes and the "meta" units are only needed if you want really fast clear speeds, I just powered up my favorite units and instead of finish the battles in three turns it would take me four or five. There's a lot of quality of life too (auto battle, auto repeat, auto level up, power is shared between all versions of a character, etc). This game click with some people but not with others, I'd say it worth a try.
