Tradewars was one of the most interesting BBS doors that I encountered. The idea is that you are a trader. You set up an empire. As you got more powerfull you could claim whole planets as your own and equip them with awsome defences. Then there were the people like me who messed with the game. There was a ship called the "Intrepid" which was supposed to enforce the rules of the game. There was no provision for the destruction of the intrepid. I found a way to kill it. --Crunch--
