Hello Andy,
Thank you for reaching out for support! I understand you’d like to set up your product home page for your game to display the OpenCritic reviews. Your game has an OpenCritic page, but there’s not a way to configure this in the Dev Portal. I’m happy to help with this!
In order to assist you with this request, please use this link to create a private discussion, with the topic set to Epic Games Store. This will ensure you’re routed to the correct support team for help.
We look forward to hearing from you!
