it would be cool if there was an fps style multiplayer game type. sorta like quake, but with space ships. first of the game would need to be made where it does not require a joining session to get into the action. you can connect to the server and start playing imidiately, starting with a default ship and weapons.
second there would be installations to dock with to get new ships and weapons, or even in space powerups that can pe picked up.
gameplay could be plain old dogfight, capture the flag, and any other game type you can borrow from fps games. i think its kinda stupid, but its an idea.
