I have had the Traveller Book since about 1984,and played only a handfull of times(most of my friends were fantasy rpg buffs)but i've always had a thing for Traveller.I am not a fan of gurps and d20 doesnt appeal to me either.(I dont really see what all these kids find so great about d20,its like the microsoft of the RPG world.)I have been interested in MegaTraveller for a while as it seems to me an extention and cleaned up version of CT.What makes it diffent than CT,also in the same respect what is the same.
