You do not need to own or have played previous Forza games in order to play FH3. The Standard version of the game costs $60 and is available either for the Xbox One family of consoles or Windows 10 PCs with the necessary performance and storage requirements. FH3 is not available for the Xbox 360 or other brand consoles. Other than a monitor the only other equipment requirement is a compatible controller ("gamepad"), which is included with retail console packages or available separately for PC use. A steering wheel, pedals, and shifter setup is not required. Kinect and a headset are not required but will enhance the playing experience in solo and multiplayer modes. An Xbox Live account is required to sign in on the console and PC. A paid Xbox Live Gold membership is required for multiplayer on the console but not required for multiplayer on the PC. Only one copy of the game on a console with Gold membership is necessary for guests on that console to play the game and have access to downloadable content add-ons. In-app purchases are not required to complete the game. See the Support topic for discussion about physical and visual impairment, and the Hardware section for discussion of technical issues.
