@LeftHandedMatt: You can trigger a manual refresh of this list after adding the proper "{{Store feature|" call to the game page. To do so, click on the More menu on the top right corner of the list page, and then select Refresh. This will cause a full refresh of the page.
If the game still doesn't appear, do the same kind of refresh on the game page, and when it have finished loaded do a refresh on the list page as well once more.
If it still doesn't appear then something is wrong with the {{Store feature| call added to the game article.
