Just avoid mobile games, I've been sucked again into two of them (Nitro Nation and GT Racing 2) and even if less than others, they're quite crappy, rely too much on obsessive-compulsive mechanisms to push sales of DLCs and/or game currency (I don't buy them, they're not worth the money, but then I have to grind even more than what I already do in many RPGs), my thumbs ache, and they stress me more than they entertain me, if I won't play them less they'll end up making me hate gaming.
