Before you play

Your game version

If game ownership is required, check that your store version and edition match the provider listing. Steam / PC features do not confirm support on every cloud service.

Your region

Check availability in your country before subscribing. Global source scope does not guarantee access in every country; a regional listing applies only to its recorded region.

Your subscription

Check the required service plan and whether the game is included or must be purchased separately. A free-to-play game may still require a cloud gaming subscription.
