We have recently made some changes and additions to the Hosted Games Submission Form to expand on information that may have been confusing before. It now includes all of the specifications and details which I’ve explained in most any other format.
If you have previously sent a game to use through the submission form that is not yet published, there’s no need to resend it, but you might want to look at the new form if there was anything that confused you, to see if you want to make changes.
Notably, this includes some minor changes to how we look at and send feedback on games, particularly with regards to appropriate promotional artwork (if you’ve ever had promotional artwork rejected please see our rules as they have been revised to account for what we think is the full spectrum of previous problems), and beta testing games (notably a list of beta testers is now a requirement, and we may send authors back to the forum to test their games if it lacks sufficient testing).
