I love this game. I like how the gacha is very f2p friendly and the fact that all of the characters are useful. You don't need a full S rank team. Some A rank characters are awesome. 5 star weapons are not that hard to get, you just need to do co-op for 3 weeks or it might even drop from co-op runs itself. Equpping good memories and weapons on your character are not so hard, it's just a bit time consuming. All in all, great game.
