If I were to rank all of the "gacha game adaptation" anime I've watched (regardless of whether I've played the game they're adapting or not):

Princess Connect ReDive > Magia Record > Last Period > Hortensia Saga > Girls' Frontline > Cinderella Nine > Azur Lane

I also have Granblue Fantasy's anime on my plan-to-watch list. Note that this is not counting original anime that set up future gacha games, like BanG Dream, Revue Starlight, Takt Op Destiny, etc., because I consider those to be a completely different category.
