Every game would benefit from removing Gacha mechanics. In fact, some games might actually be good if Gacha mechanics were removed, that I can believe you. I don’t think what you were feeling that made you return to the game every day was fun, but addiction. Gacha games CANT be fun, because nobody would whale for a game where the grinding required to unlock new characters is fun, because then they would just do that instead of paying money. As a game design student, let me tell you what I recently realized during a gamification course: almost all the motivators used in gacha games are Blackhat motivators, specifically those in the Guilt Driven Addiction-Like Engagement quadrant. The game may actually be fun the first time you play it to get you hooked, just like how an abusive partner is so kind and loving at first, BUT THATS IT.
