xbox 360 controller support in forza horizon 3 on pc?

Forza Horizon 1 is an Xbox 360 game, and as such will not work on the PC.

Hello Juan!

Thanks for reaching out to us here on the forums with this situation. I understand you're trying to play Forza Horizon 4 with an Xbox 360 controller on a Windows 10 PC is that correct? It could be the older controller may not be compatible with this Xbox
One Play Anywhere title. Take a look at this support article:

Hi Brett

Below, find the list of wheels currently supported by Forza Horizon 3 on Windows 10 PCs. On Xbox One, Forza Horizon 3 supports all wheels currently supported by Xbox One.

The list of currently supported PC wheels for Forza Horizon 3:

Thrustmaster T150
Thrustmaster T500 RS
Thrustmaster TMX V1
Thrustmaster TMX V2
Thrustmaster T300RS
Thrustmaster TX
Thrustmaster RGT
Logitech MOMO Force Feedback Racing Wheel
Logitech G920
Logitech G929
Logitech G25
Logitech G27

Players can use the Logitech G27 and the Thrustmaster TX (and some TX variants, like the new Leather Edition), but these wheels have some limitations with their functionality in-game. While these wheels work on default or custom wheel settings, button mapping and force feedback are not properly recognized. These issues will be addressed in an upcoming update for Forza Horizon 3. In addition, there are additional wheels that we plan on bringing on board, notably Fanatec products such as the ClubSport V2 Xbox One Hub and the Fanatec CSR models. Support for these Fanatec wheels will be arriving in Apex beginning in late September, with updates for both Windows 10 and Apex.

From this, unfrotunately G923 is not compatible with Forza Horizon 3

Hi, unfortunately Forza Horizon 3 is available only for the xbox one, therefore is impossible to play with it on the xbox 360... if you are unable to use it also on your pc, you can try to contact the xbox support in order to verify if you can get a refund,
you can contact them here: https://beta.support.xbox.com/help/...games-apps/digital-game-purchase-refund-terms
(on the right you have the button "contact us")

If you want to buy a similar game for your son you can try to find a copy of forza horizon 2 (available also for xbox 360), you can try to find a phisical one (be carefoul that you need a copy for the xbox 360) from amazon or other shop or a digital copy
on the xbox marketplace here: https://marketplace.xbox.com/en-US/Product/Forza-Horizon-2/66acd000-77fe-1000-9115-d8024d530aa4

Moreover note that a digital copy of forza horizon 3 can be used both on xbox one and windows 10 since it is a xbox play anywhere game (more info here: https://www.xbox.com/en-US/games/xbox-play-anywhere),
unfortunately forza horizon 2 is not available for PC.

all the other forza games are working fine, even forza horizon 2 on xbox 360, iv tried tweeting forza support, no reply, iv opened a ticket with them and its solved instantly, even tho it says there is still limited support for matchmaking. i just saw the post here for forza horizon 3 and that got it fixed so thought id give it a shot here.
