Back when I was first getting into Traveller around '99 or '00 a friend and longtime Trav fanatic warned me off purchasing a large lot of Judges Guild products. The lot consisted of one or two of their adventure modules and two or three of the sector books. I know the JG material has been de-canonized and that T20 products now covers the same part of Charted Space. What was the problem with the JG stuff? My friend thought it was sub-par but really never gave me any details. I still occasionally search eBay for Judges Guild material for D&D and when I see the Traveller sector books and adventures I can't help but wonder what's inside.
