where those phone games, "built around a new generation of super-precise haptic feedback, employing dual linear resonant actuators"?
Aside from resonant, which is irrelevant bullshit as far as actually controlling something with the pads is concerned, the answer is yes. Games were optimized for the Xperia Play, which means they had support for dual analog controls. That's precisely as "built around" this controller as most Steam titles are going to be. They'll work equally well with a Sony controller, which has most of the same functionality more or less, albeit with analog sticks instead of gimmicky touchpads. The Xperia Play also has dual touchpads and it sucks to use compared to dual analog sticks. Dual analog sticks won't fit on a phone, but they will fit in a console controller.
I declare Sony to be the winner of the controller design competition. The PS4 controller has tilt, touch/tap, dual analog sticks, and IIRC six analog buttons and two analog triggers. ObDisclaimer: Sony can go take a flying fuck in a rolling doughnut, and I won't be buying a PS4. I just think they have the best controller in this generation. I will be happy when they are available used.
