Corellian Corvette, alias Blockade Runner, is the first ship seen in the first Star Wars movie... In the game world, it is widely used by rebellion and other factions also.
Marketplaces are very common element in all roleplaying game environments. In medieval era - and fantasy worlds inherited mainly from that era - marketplaces were vital, as most people or their servants went to fetch food from marketplaces.
Another crazy project of mine. Some days I think I have time for everything, and I try to do everything... I was preparing ground combat rules for very small scale Star Wars miniatures, but I never got them finished. I've got a bunch of scratchbuilt or modified small miniatures though, and now that I've found Savage Worlds and it's mass combat rules, I can create battles using miniatures as counters! If you're a Savage Worlds fan, you might want to read my post about starship battles.
