We are getting married and moving to Aruba.
Actually the only difference I see between using the steam controller setup vs your new virtual setup is....
The ability to select the folder icon in the build menu. You cannot seem to hover over that when you are using the steam controller.
A win for your virtual cursor as I can hover over that icon with it
The texture and color select. With the steam controller setup you have to click on the textures or colors and then select what you want. A win for your cursor as you can move right to the color or texture far more easily.
The one down side I feel is the loss of the dpad controls in the menu. If you brought that back I feel it would be the perfect substitute for us players that are mouse and keyboard inept.
Attached are poorly taken videos of the control functions using the steam setup in the original game.
One more thing to note but I'm not sure you all can do this. The controller to keyboard mapping is weird. Some inputs are crossed and when allowing MandK players to use our builds they cannot. It would be nice if you could figure out how to remap the control so the keybinds would match up more smoothly with what a MandK user would use.
