JavaScript has no ability to WRITE to files.

Not 100% true; MSIE can write to files ON THE USER'S COMPUTER (only), but only if the user marks your site as being a "safe" site and only if he/she agrees to let your page run an "unsafe for scripting" ActiveX control.

But even here, the JS code is only writing to the USER's computer. No matter what, JavaScript has no ability to write to files ON THE SERVER, which is surely what you would want to do for your map game.

You will need server-side code (PHP/ASP/JSP) to do this. And then the JavaScript code *can* send the data to the server and let the server do the file writing.
