Ahhh the monster collecting game where catching monsters is useless compared to rolling the gacha.
I believe this is technically a paid game, but I got it for free a long time ago. I kinda had fun with the campaign, then after finishing it I realized there was no other content in the game like it. No more exploring the "open world", no more catching, no more of what the game description says is it's selling point. What's left is a continuation of the story through additional chapters that were just battles and vn cutscenes, that and the online. At that point it's just a generic gacha.
