Efate: One of my favorite destinations in The Spinward Marches.
LBB Supplement 3 gives in year 1105.
Regina 0105 A646930 D N Non-industrial. Imperial Way Station.
Starport A, 6,000 mi dia, Thin-tainted atmo, 60% surface water, billions of people, self-perpetuating oligarchy, no laws affecting weapons possession or ownership, above imperial average TL, Navy Base. With a population code of 9, it's not supposed to be non-industrial...
LBB The Spinward Marches Campaign gives in 1111.
1705 A646930-D B Hi In 800lm K4 V
Starport A, 9,600km dia, thin-tainted atmo, 60% surface water, billions of people, self-perpetuating oligarchy, no laws affecting weapons possession or ownership, above imperial average TL, Navy Base and Way-Station. High population. Industrial.
GURPS: Traveller give in 1120.
Starport: Class V. Way station and naval base.
Diameter: 6,339 miles. Atmosphere: Thin oxygen-nitrogen, tainted by a low oxygen content. Surface Water: 60%. Climate: Cold. Population: 8,373,000,000. Government: Military (naval governor). Control Rating: 4. TL: 10.
Even considering the differences in game systems... The government, law and tech levels have changed.
GURPS TL10 is Imperial average, a B or C in LBB terms.
Control rating of 4 which allows "hunting weapons like single-shot laser rifles, knives and other low-tech weapons. That's more like Traveller law level of 5!
Efate being controlled by the military kinda-sorta fits self-perpetuating oligarchy...
Since the differences aren't in the same year, one could come up with why there was a crack-down on personal armaments. It's just the place was so handy for the players to stock up on high-tech military small arms and get better warheads for the missile racks.
