One of the unique things aboutStar Wars Galaxies is a player-driven economy — and we mean driven. Players can own shops to sell their crafts. In addition, you can have factories that mass-produce items for sale to other players.
The lonely crafter, squatting in a corner and simply churning out goods, has been upgraded into a store owner, complete with a staff of workers.
A great many items are available only through the efforts of Traders. The best armor and weapons, for example, are going to come about through highly skilled player characters.
Anything and everything is for sale these days. However, each server has its own independent economy. Browsing the trade boards available at https://swghope.com/forums/forum.php (Under the Trade heading) should give you an idea what is selling for what price. Test Center has the absolute lowest prices, with Bloodfin usually sporting the most expensive prices.
A good way to gauge the inflation level of a server is to take a basic +Experimentation Attachment. On Bloodfin, a +1 Armor Smith Experimentation Attachment goes for over 1 million credits. On Test Center it can go for 2000. Quite a difference in price, wouldn’t you say?
