Mortal Kombat X....so addictive.
Most of the games on my iPhone/iPad are JRPGS (Final Fantasy and others) and the Telltale games like The Walking Dead, Game of Thrones, etc.
I still play Words With Friends....
I play Avengers Academy.
It's technically free but I've spent so much god damn money on that game I'm ashamed. They're really good at luring you into giving them their profits from the freemium model.
