Actually, I don't think it would be all that hard to simulate a battle school battle. You just wouldn't have the particular characteristic of weightlessness. Like I said, encourage the participants to use their imaginations.
But, Cloud's idea isn't a bad idea at all. You could be a battle school instructor explaining to a new group of recruits exactly what goes on in battle school.
Anyway, Filicireg, I hope some of what we've come up with will help you out with your assignment. Be sure to keep us posted on how you are coming along with it.
