I need a piece of software developed in JavaScript. The basis of the software I need developed is for other people to use my software to create their own 2D Mmorpg game without having to know how to code each thing they do with the core functions will auto code everything for them including server side so that each package gets sent to each client without the creator having to code anything . There will be many stages to this project.
