I have been playing gatcha games for a while now off and on, and I am totally over them. Kingdom Hearts Cross X, Final Fantasy Brave Exvius, Final Fantasy Record Keeper, most recently Star Ocean Amnesis... I recently threw my hands up and have pretty much said to hell with them. Unless you're pouring money into the games - which I do not - it is very hard to stay ahead.
The only one I'm mostly okay with is 3DS Yokai Watch games. There's a gatcha element to it, but no real currency can be used outside of buying the actual game. But still, it's frustrating to have to rely on luck and chance to obtain some yokai. Japan has a few Yokai Watch mobile games, and I suspect that they are just as bad as the actual ones.
Gah! Burns me up.
