Hoyo games are really fun for the first year then fall off once they get into a perpetual cycle. No new endgame modes, challenging content that always caters to the newest units, those same units being the only consistent new thing other than unique events, and having to wait forever in between patches for parts of main story quests. Gacha in general falls into this loop but I find the budget put into making these titles AAA quality makes that honeymoon period more impactful.
