I like Mongoose Traveller 2E. Its got the foundation of classic Traveller but a few modern touches just where they need them. Traveller doesnt have leveling in the D&D sense, so the system while mildly crunchy, wont change much on you once you got the basics down. If anything, there is an SRD so you can get a free peak at the 1E ruleset.
Hope you check it out, let us know if you do!
One of my friends just bought all the traveller stuff so I am hoping he runs us through it. My next purchase is definitely going to be traveller. Can I ask what the major differences between the original Traveller Books are and the Mongoose stuff (I always hear good things about Mongoose but I am curious if there is value in reading the originals too)
