Software development is my profession, and I have done a bunch of Lua scripting in games like Second Life and Legend of Grimrock I & II and scripting in other languages such as Javascript for games like CodeSpells. As a result, I will likely gravitate in a huge way towards construct building and sales. I will also be trying to get into the earliest possible alpha / early access program they make available through Steam or Kickstarter or whatever. As such, I hope to grow a huge manufacturing and sales empire in the game. From this perspective, I have a few comments:
It is probably inevitable that certain resources will become dirt-cheap (literally) in the markets, others will have greater value. As a builder, I would rather spend my time constructing and coding, rather than mining and gathering resources. I would prefer to leave resource gathering to newer (or more dedicated who can handle that grind) players and just buy them off of the markets. Depending on how many people gather resources, I may pay more or less for them on some days. At first, I probably won't have much cash on hand, so I'll focus on smaller items that I can build and sell quickly in order to generate the revenue for larger products to put up for sale.
According to the DevBlog, much of the markets will be automated. You post a buy order at specified price. Someone who has the resources posts a sell order. If the two line up on cost, it will automatically post the transaction for you. You shouldn't have to babysit the location for sales to go through.
As to scripting the constructs, I will certainly be one player developing scripts constantly to make things bigger and better. I may even contract myself out to players from time to time to code private scripts if they can't do it themselves. So there will be at least one, but probably many people to assist with that sort of work. Contracting for script coding, means I will have more capital to buy more resources so that I can build more products to sell later.
My product prices will be based on the amount of work I have to put it to develop the prototypes and cost for resources plus a bit of profit. From my perpsective, that will balance out nicely as I won't short-change myself.
I plan to set up a base right near the Arkship so that all of the new players will be able to find me right away and Know I am the one to go to for the best constructs.
EDIT: For the grammar police.
