Well, to start out with, Traveler was the second game I ever played in 1977, just a few weeks after I started playing Dungeons & Dragons. I think the pulpy goodness and the references to the Age of Sail give a really great roleplaying environment. Traveller really created the concept of the big story arc within the game, and the lifepath system. Both really give you a lot of information that you can use to create a fun character. Combat is pretty deadly and I think that helps encourage role-playing. There are some anachronisms and things that don’t really make sense in a modern context. However, I think you can really leave those if the rest of this setting makes sense to you.
