The problem is that the name "Traveller" rather suits the setting nicely as is - it offers a sense of exploration and wonder, with implications of adventure, but lacking any forced notions. It is Simple and comfortable, giving the brain plenty of room to wander without being forced into any preconceived notion of setting. What always impressed me with Traveller was the sense that the setting was designed to conform to YOUR adventures, rather than forcing your adventures to conform to the setting.
