I don ' t get it . I think the market risesfalls on its own and a fitting rationale is attached to it , which to me is completely random . The market is not some mystical isolated entity with a will of its own . Rather it is a lumbering unpredictable entity which is influenced by a number of complex factors . Markets rising and falling depends on investor sentiment which in turn depends on what they know hear feel . That is why it is difficult to anticipate the market because it ' s literally impossible to understand all the elements in the equation . Also the saying hindsight is 2020 is especially true in the case of stock markets . <| sep |> hahaha uv for title <| sep |> Think to keep in my about SC is that economy is going to be handled as a sever side simulation . NPC agents aren ' t actually going to pick up goods from A and fly them to B . It ' s more general than that when players don ' t pick up the jobs with the server spawning NPC ' s the represent the trades it ' s handling into actual instances with players . An easy to understand example is NPC pirates . There aren ' t actual NPC agents being simulated but an area of space in which the server says npc pirates are active here to this extent . This then impacts the trading simulation some percentage of trade jobs not being done by players don ' t arrive and makes it ' s more likely that a player in that area will have NPC pirates turn up with in an given instance . As players kill pirates or as jobs to clear them out are posted and completed the pirate heat in the area will go down . The real reactive part of the simulation happens at the economic node level . These nodes are what posts the jobs for hauling of the goods they need and can both grow and shrink as needs are met , or not . Which , to bring it back around to the point about the OP , is why I think trading of this kind is far more prevalent in space games . It makes abstraction easier . To do something akin to this in a fantasy setting makes that a lot harder especially at the population scales of most open world RPGs .
