I was wondering, if Edge of Empire could be used as a system of playing campaigns similiar to Traveller, where you can buy cheap and sell with profit. But the rules in Core Rulebook provide only one guideline for determining prices, which is rarity depending on which Rim the planet is. It's very poor... It leads to situation, where all planets in one rim have identical prices. Are there some better rules for it in some supplements? If not, the only way would be to use tables from other games, like Stars Without Numbers with Suns of Gold supplement, or Traveller, I guess.
While Edge of Empire is brilliant game, it is sometimes lacking in economy and resource management rules. That's why I really like what they did in Far Horizons. However I don't know if it's a mistake. Buying a business costs 50,000 or so, and it generates only 100 credits monthly? It would be absurd.
