MiniRPG is a project mainly written in ..., it's free.
A minimalist RPG - developed for learning how to program games in JavaScript and PHP
This project has been set up to help the 2011 'Automate Processes', 'Scripting in Another Language' and 'Maintain Open Source Code Programs' subjects at the Hobart Polytechnic.
We'll be building a basic RPG game here using JavaScript and PHP (and git, obviously).
