I saw the title of this thread and got excited thinking you were talking about something like Netrek: Hockey...
Netrek Hockey is a cross between Netrek and, you guessed it, Ice Hockey. The planets are laid out to form a rectangular hockey-style rink, including goals. Ships use tractors and pressors to shove a puck around, fighting with phasers and torpedos as needed to get enemies out of the way.
Which I think would be pretty awesome PvP training mission.
Edit to add: Mission would be using specialized Miranda class ships.
