there is hardly anyone in the game for Alpha to test a real market and economy. come on guys this is 101 stuff, you cant judge market based on little over 100 players when the game is designed for thousands of players at a time. You guys have no real risk of theft and loss yet, not enough players to count in the risk vs gain and loss. And those that are, are also trumped by the same low numbers. Thieves are more active when there are many many players to choose from, market places only function well when there are many many players to work from. Look at world of warcraft, beofre the xrealm and merger of auction houses, lower pop servers had a shitty shitty market place for players. You went to a high pop server, you could find not only what you needed but at a better price and in more bulk.
Until there is an actual population, the only real thing yuo guys are going to be testing that can show any real data with low numbers is the basic functions of the game. Error reports, structure building, ship flying and mechanics, weapon mechanics, mining data(but at a minimum, lack of bodies to judge more data from), GUI errors and structure such as Invetory, Friend List, Company tabs and so on.
Once they have a population, than you can run real tests towards market places, economy value in goods, risk vs gain and loss.
EDIT: Also without a enough players to base info off of, think about this, if we got 5k players, 35% of that 5k decided to be thieves and pirates, yuo do know that is a drastic change on market value.
