I'd like to know if AG provides any server like electroserver or smartfoxserver for free which i could use for a submitted content and while i'm developing the multiplayer game
Well as for Servers, I'm pretty sure we don't have anything like that. As Kongregate has some kind of API thing. But AG doesn't have anthing like to my knowledge. YOu can contact the Owner here.
Or you can email Dan McNeely, the owner, at this adress. Daniel@ArmorGames.com
Krin runs Colony on the Blossum Server, which was made by Jiggmin. And Platform Racing 2 runs on something similar, also made by Jiggmin. If you are thinking of adding one to your game and you are willing to pay, go to jiggmin.com and contact him about it. But that is all there really is at this point.
AG doesn't provide anything I don't think, but like Cholo said Jiggmin provides some, nonoba also provides some, but it isn't that good...as long as your willing to pay a high amount.
