(scroll to the end for TLDR)
One of my favorite casual friendly gacha game with a good pity system. As someone who played Arknights first, thought it would be a shitty version of that game… but currently I’m enjoying it as much as Arknights. (P.s. I also thought Arknights would be a shitty version of Bloons td so yeah…)
Character design, art, and animation (L2D) are outstanding. Story is also really good. It’s casual in a sense that there aren’t any real competition so you can play it at your own pace. And you won’t even be spending much time doing dailies cause there’s quick clear for almost everything so it will take like 10 to 15 minutes if not less. Rarity of characters don’t even matter. I can guarantee you that in some game modes/stages, there will be specific free low rarity characters you will absolutely need as they will out perform many high rarity characters. And as far as buying in game currency goes, you’ll get a LOT of it for free (you get 40 from dailies, 48 from an auto generator thing and 150 from weekly, and bunch more from events and so on. It takes only 1800 for 10 summon….). The only one you won’t get for free is for buying skins and that can also be converted into summoning currency even though that’s completely stupid to do (Imo).
Now, as far as cons go, there’s a lack of content in this game form time to time like most gacha games. You will find many levels hard to beat at the start if you don’t read character skills/enemy skills or skip through tutorial (pro tip: watch youtube vids if you’re really stuck lol). Leveling characters takes time at the start and you need to have variety of characters (so don’t waste all your resources on one character). And there are some game modes (mostly “end game” content) that are very difficult to beat and here’s a video of one of them ( https://www.youtube.com/watch?v=Y1f6sgK5nYs&t=29s ). I doubt it will make sense to anyone that hasn’t played the game or it might even look simple since you won’t understand all the “micromanaging“ stuff but just know that this shit can be difficult (you get 510 summoning currency for clearing it with a good score weekly).
Overall, outstanding art, good story, fun and very casual gameplay (some game modes/levels can be extremely difficult), lack of content from time to time, leveling takes lot of resources at the start and very very f2p friendly (UNLESS you’re dumb af and don’t save/spend properly).
