They supported google's standard.
MOGA uses(used?) their own library for controller support, CTRLR uses google's standard controller support.
I expect more devs now to drop 3rd part controller support and only support google's standard.
Is MOGA BT4? I don't think it is.
MOGA doesn't support PC/Mouse mode.. which I use as a wireless mouse on my laptop sometimes..
And that is good because that means you can use allot more games, then only the google's standard controller support, whats the MOGA Pro
Controller also can use, without problems.
If you need Bluetooth 4, it's only handy because it uses less electricity, and you can simply use the tough screen to start Apps on a Tablet, or use a
cheap mouse so thats also no problem, when i used the Mad Catz M.O.J.O. i only used my air mouse, worked allot better for me then holding a
JoyPad with two hands, i only used the JoyPad to play games.
