Boring as fuck. I stopped playing it because the gacha system is atrocious; I hate it when mobile games put weapons AND characters in the same summoning pool because you're more likely to get shitty weapons than characters.
Re[in]carnation's story also hasn't connected to the Nier console games yet and truthfully I don't think it ever will.
Re[in]carnation is clearly just a crash grab SE and Taro is milking for money.
