I can't believe people actually play this crap, my calculator is a better videogame and it's not even programmable.

The game essentially plays itself and all you have to do is gather resources (via ungodly grinding or paying real money, neither of which are valid) to make your party's number get bigger.
If your number is bigger than the enemy, you win.
I don't know why they pretend to have a battle system, it doesn't really matter.

Avoid at all costs, this is the only gacha I tried to play because I love this series, but not even my blind faith in Nier could make me stomach the insult this "genre" is to the medium.
