For me the best ones were Final Fantasy Brave Exvius and Love Live School Idol Festival. Currently playing Umamusume Pretty Derby and it’s fine but it’s kinda brutal if you’re trying to catch the meta as F2P.

Also gacha games are fine at launch (and maybe just before they close the doors forever). Other than that they’re just whalefest, especially if they’re popular.

No idea how long I’m gonna stick to Umamusume but I feel it won’t be years.
