Batman Arkham Origins on the mobile is interesting as you play the beginning of Batman joining an alliance with Gordon head of the police and also there is Bullock, who does not like Batman and is wary of his actions. I like how the fights can go easy or hard depending on the situation in the game and like the gadgets you can use and the Batarang which can knock the people out. I would also recommend Godfire: Rise of Prometheus which is based on the titan Prometheus who is setting out on a quest which will involve battling demons and warriors to get to his goal.
See, I have problems with Hearthstone even on my PC, and yet I can run other things perfectly fine on my PC, so I'm not really sure what it is, but that doesn't help me trust it much, haha.
