Well if the game has a button to add the game to a website of yours then it could get added to somewhere.I don't think necessarily AG,because of the legal issues that would cause,but I think it could be added to a fan site of AG such as Armor Wiki,or one of the clan sites that have been made.
Please contact The Administration in an e-mail stating the game name, link, and game creator. They will ry their best to get the game on armor games. That is if they like it ^-^
You can only submit a game on this site if you have personally developed it. If you have not, but would still like to see it on this site, you can always contact the developer and ask them to submit it themselves.
