You can find specific additions based on what moderators have told me below.

The following are guidelines located on a hub that you have access to and can edit under options tab.

Before you check the box making this hub visible to BYOND Moderators, run through this checklist to ensure your game is ready for review:

1) Games utilizing released or leaked source code, artwork/graphics or music/sound are subject to rejection. Having many games visible on the site that are very similar to one another is not ideal.
2) Games using free resources such as sprites, artwork or music/sound should have a footnote on the game's hub citing the free resources used. This expedites the process on our end and will see the game listed sooner.
3) Games utilizing the intellectual properties of FUNimation (i.e. Dragonball, Dragonball Z, Dragonball GT, Fairy Tail, etc.) or Square Enix (Such as Final Fantasy) will not be listed due to a cease and desist order given by their property owners.
4) Games should be playable upon submission for review. If a game is deemed to be incomplete, it will be given the status as incomplete.
5) Upon submitting a game for review, there should either be a server available for the Moderator to play-test the game or a download available on the hub. If a way to test the game isn't made available, the game will be marked as incomplete until the game is testable.
6) The game's hub must have a meaningful short description, describing the game in a sentence or two.
7) Vulgar language is not accepted.
8) If the game has a download link, it must be working.
9) Fangames are not permitted to make a profit of any kind. You cannot sell subscriptions, take donations or sell in-game benefits at all.This is a list of guidelines I know that game listing moderators use when deciding to approve your game listing. Any contributes to this list are appreciated. Just post guidelines you know for sure are used by game listing moderators.
