oh boi the this game is probably one of the most controversial one because of one thing - Gacha
ill be going mostly with why this game is good and won't talk about
The game starts with selecting a character (which is basically a gender selection but no one cares about gender and pick the one they like) and starts a cutscene which they unilaterally gets crushed and the one you haven't picked gets kidnapped blah blah blah like a typical game plot. But we're talking about visual here which theylldtart it directly after the cutscene . The visual is just top notch and unless any company has the budget to make a AAA game worthy then this game will be unbeatable for a open world action rpg because it simply is too good in visuals or even music. The lore isnt hat great at start but gets pretty interesting third region which is a bit dark (imo) .
Anyway the artstyle is what makes the game sreally special and it's free to play (with gacha ofc) is the best if the only thing you care about is story rather than getting the characters.
