Hi,
I have been working on a Paintball Manager game for a while. Idea is same as in any sports management game; you get a team, which you try to turn into best team in the world. Quite important part of the game is creating tactics and watching matches. I did not want just textual presentation of matches, so Java came in handy. I used JOGL to create tactic editor and match viewer.
Screenshot of tactic editor. Here you can give all kinds of orders to your players. E.g. run/walk/sneak here, shoot at here…

It’s quite complex game, but if you happen to be interested please find link below. If you don’t know anything about Paintball - don’t worry, it’s really no requirement.
