Hello SMS!
First of all - there is a simple solution, but a long explanation.
Could you please change the button that Starts Up this beautiful game, from "Start/Menu" button to "A" button on Xbox One - just like the PS4 owners have their "X" button to Start Up the game.
The reason is - some of us enjoy this amazing game with an aftermarket wheel (with no buttons) on the Thrustmaster TX base, and tho we can finally navigate the menus with the XB1 controller, we can't start the game with a controller, and then race with the wheel, because the game then thinks we wan't to race with a controller and not a wheel. Which can't be changed in-game.
The thing is - the "A" button does the exact same thing as the "Enter" button on a keyboard, which works in the game on Xbox One also. So if "A" was the button to start up the game - so would "Enter" be on a keyboard.
A simple solution would be: change the button that starts the game up on Xbox One to the "A" button just like the PS4 already have it. (only it is called the "X" button)
Please, please make this little change on the Xbox One version.
