Not just a gacha, even when every of its mechanics is tailored for grinding. Ridiculous limits and restrictions don't hinder the gameplay and fun of wandering around, exploring stunning locations with atmospheric soundtrack - probably the best part of the game. The story is good and has its highlights, there’s characters tailored to every taste and the dynamics between each of them are rather fun. Grinding based on gamble luck and bound by limits designed to take your time and keep you in the game are not. There’s always an illusion of choice - you can choose not to better your characters and their damage, while still enjoying everything else the game offers. Even though updated often and regularly, some of the events feel very similar and can be a bore with their worn-out mechanics. I don't regret playing the game however and with it constantly expanding with new locations I’ll continue doing so for a long while
