My biggest problem with Uma Musume is that you can see from miles away how Cygames will turn it into a hardcore grindfest (or you can just watch the OG server). This very first event required a shitton of runs, and practically you have to skip all events and texts, which its a shame since I do think this is can be a sweet casual visual novel / training sim.
Then again, you can just ignore all FOMO shit and enjoy it the way you like. Its a gacha and that sucks, but then again, it will keep being updated for a while and for free. I still don't know if I'll keep playing it or I'll become burned-out after a few days.
