So, I just go this web server that has a ton of bandwidth and a ton of space to host my graphic design portfolio and I need to do something with it. Does anyone know of a open source game engine for online games? Something that works with &#106avascript/AJAX, mySQL, HTML, Flash, etc? I want to brush up on my web development skills and figured this would be the funnest way of doing it. Doesn't even have to be open-source. I'm looking for something that can handle user information, keep high-scores, and include multiplayer support as the bare necessities, but any extra bells and whistles are welcome.
