WARNING: You will have to be confident programmer to pick up a project of this size.
I was asked to repost the thread with more information and pictures. Imagine logging into a game in your browser, walking around the massive world of Pokemon and then seeing your friends around around with you?
When I was a kid I had this vision and wrote a game engine that made that possible.
I took a number of design decisions to support interesting things in the game engine that I had never seen in other fangames. Namely:
This project is better suited for more advanced developers and not for the faint of heart. You'll need to be familiar with Apache configuration, MySQL databases, Java sockets to work on the server.
I am releasing the codebase because I no longer have time to work on it but someone else may find it useful. I have so many ideas but not the time in the world to work them through. By releasing this, I may have saved some people lots of effort so you can pick up where I started.
