Its hard finding all that canon material. I'm a newcomer to Traveller, only seeing it in the CT reprints, though I've 20 years sf gaming under my belt, but I fell in love with it immediately. T20 was a must buy as I know the D20 back to back, and QLI have done an excellent job of marrying the two systems. Well, enough biog. Just thought I'd explain my background a bit, since you all seem to know what each other's about.
Its almost impossible to find any Traveller material not sold online in my neck of the woods, which is why I gobbled up the CT reprints so quickly, so I have large gaps in my knowledge of canon. Sp please be gentle if I post something stupid.
However, I do think there should be no rush to generate subsectors. My only real critique of the Spinward Marches is that it was really hard to work out which planets were important: the high tech industrial worlds that would obviously dominate the economy.
Maybe we should work out trade routes and economic factors before doing all that number crunching. Also maybe we should look at 'adventure planets', places where there's lots of opportunity for different kinds of game, and done in enough detail to allow people to get stuck in straight away. In the Spinward Marches I ended up getting drawn to Tarsus, which seemed the ideal place. I don't seem to be alone in that, considering the amount of stuff I've seen on the web. We should consider scattering a few of these ideal adventure planets around. There could be a gold-rush style colony world, a wartorn planet, a pirate haven, etc.
Talking about pirates, we need to work out how that economy works too. It seems ridiculous that Granicus could be a pirate haven, as its almost isolated in a rift. For pirates to operate, and to be able to strike at Stoner and Imperial targets, would need a massive network of secret deep space refueling points, and therefore a massive criminal organisation to support it, which is just not implied in the literature. We can avoid such anomolies if the Spica sector is 'designed' rather than 'generated'.
I also have some ideas about corporate 'free trade' zones and independent traders/miners (somewhat Firefly inspired) and how that conflict could work out, especially with the war as a backdrop. I apologise if I'm covering old ground. I should get up to speed soon.
