Provide direct route for gamers to get in touch with developers
As with routes of feedback on console accessibility, knowing how to get in touch about accessibility information on games is a common source of frustration, particularly as gamers do not always understand the platform/publisher/studio relationship, let alone first/third party studios and so on.
So providing a well-publicised high level service to gather accessibility feedback at a platform level and ensure it reaches the right teams would be extremely valuable.
Providing a means of contacting developers directly through digital storefronts would also help.
