Dol Guldur - MERP and Rolemaster Traveller Traveller was the first Roleplaying system I played in 1983 . It was and still is a fully developed Science Fiction universe set thousands of years into the future . These are a generic set of rules you can down load from the net. They seem to work quite well. Background material is very complete .
Maps are great.
I will try and put on some details of my campaign . This site has extensive files relating to this 70's RPG system. Looks quite good.
