This edition of Micropolis, written for the Java desktop platform, is fairly feature complete. I believe the only missing functionality is that of loading the built-in scenarios, and this can be implemented if there is any demand for it. I will soon update the home page at http://code.google.com/p/micropolis/ with downloadable packages of this edition of the software. git-svn-id: https://micropolis.googlecode.com/svn/trunk/micropolis-java@528 d9718cc8-9f43-0410-858b-315f434eb58c
