the problem too with finding nice trade routes, is that once you find them, thats it you're done. so you zip back and forth from point a to point b. sure it'll make money, but at least to me, it seems kinda boring. but I guess thats what the pirate activity is for.
the idea about the economy "leveling out" makes some sense, but it wouldnt level out to static. someone said a small flux range of +/-300 or something similar. that would make the most sense. thats enough money to not have it theoretically matter for the stations, but certainly enough to matter for a small time freelance guy trying to make a buck hauling cargo. you find out that they need commodity X at station Y. you purchase commodity X someplace else for a lowe price, and upon arrival at station Y you discover a freighter carrying commodity A docking right in front of you! and THEY get the best price deal not you. the price goes up, you lose some (maybe all) of your profit so you can then choose to either sell and take the profit loss, or not sell and try your luck elsewhere.
now granted that makes trading much much more frustrating. but that is what a free market is. keeping with the appearance of a living (not actual) universe FL already has, one could easily accomplish this with the random price fluctuations of elite. sure one could sit outside the station and wait for the prices to be favorable, or dock and relaunch like we all did in elite to get a good price, and sure thats not fun or realistic. but then again neither repeating the same trade route over and over again. so it really kinda depends on how one roleplays Trent while they are playing. similarly one could roleplay trent I suppose to not fly the same route over and over again to make a profit also.
anyway my point is dynamic pricing has some advantages. thats all.
personally, once the full game is out, I'm curious to see if one could really play as just a trader in the game. I presume this would have to be one person on a MP server mode or something to avoid the SP missions. but it'll be interesting to see if one can really make it work, and more importantly, have fun doing it. it'd be fun (to me at least) to see if someone can get rich without firing a shot.
