I have installed jMonkey into Netbeans with the Java SE, so I'm ready to do some designing

However, we need to start brainstorming what will be in the simulation. My ideas so far is:
1. Visitor Center Scenario (learning what an RBE is)
2. Becoming an Atlasian
3. Emergency Scenarios such as knowledge database server frying

, power outages, water purification systems fail, et cetera
4. Overall design of city (be able to walk throughout the city)
It would be great to actually make this like Second Life, where one can actually "live" in Atlas City and collaborate with others in the virtual workshops and learn in the universities. Eventually I would love to make our educational center so advanced that it would take on the similar approach that the University of Pheonix is with being able to get degrees through online class, but only think about being able to take classes online, in the simulated Atlas City and actually get a degree for it.
Anyways, I would love for ideas.
