I've been playing Steel Diver, sub wars, on 3DS. Free game, quite good. Worth a look at.
Don't play games on my phone, by principal.
A: Phone is for work, and I have to keep it on me at all times. And I don't need to be hauling addicting games with me 24/7
B: I generally disprove the use of a phone as a gaming device, particularly when I've got a drawer full of Gameboys by my dresser, and a collection of perfectly great games, many of which are backlogged.
Also been playing a lot of minecraft. Just upgraded the server with 4 more GB or RAM, and got a SSD to put the world data on, to hopefully improve performance.
