I would think that the game would be simulation between teems (computer controlled ships) that the player could freely create. Also the maps and ship locations on the maps would be fully free. The player supposed to be able to store the teams and the fights to be able change teams and other fight settings. The playing would be looking already ended simulations with players own speed and camera settings.
Duels between real players could work too. Both captains against captains (ship vs. ship) and admirals against admirals (fleet vs. fleet).
