Very good questions - I almost forgot that you haven't played the game!

- I am a huge fan of teamplay in RTS games and never, ever play a standard RTS in free-for-all (FFA) mode. I have to state that preference to show how significant it is that we only like to play Offworld in FFA mode; it's easily the best FFA RTS I've ever played (which is, admittedly, not saying much). The problem with FFA in a typical RTS is that the potential for direct conflict leads to lots of diplomacy/kingmaking problems. In Offworld, direct conflict is possible, but limited, sort of like the robber in Catan. So, I understand if you are looking for a team-based game, but I hope you give Offworld a try as it is perhaps more similar in player dynamics to a good boardgame than a typical RTS.

- The stock formula is being tweaked all the time, but - yes - it is sort of a sum of all your assets, including the stock you own in other players. There is a bit of a steamroll effect, but that isn't always a bad thing. As a design, you want to minimize the amount of time players are still in the game but cannot win (a big problem in RTS games). The ideal situation is that TWO players start steamroll and then have a final conflict at the end to determine the winner. (Player A buys out players B & C. Player D buys out players E & F.)

- There is a different base price for the primary and secondary resources (so that steel starts the game more expensive than iron, for example), but it's a fairly minor effect. Prices can swing violently during the game itself (so that, for example, iron might suddenly cost more than steel, which means it's time to turn off your steel mills and just sell iron and buy steel directly).

That actually sounds really interesting, give the last player part (or all) of their buy out money and let them work their way back into the game. Maybe they can buy back into the game if they have enough cash? Atleast that way, the lead player can't just buy out their strongest opponent, and then crush the weaker ones.

From the sound of the game it should continue to escalate so that you'd have no chance of catching up to the leaders as they gobble up more and more players, but I like the sound of using the buyout money to invest in the game as a way to keep people engaged. Since you'd have no asset holdings or operations you wouldn't be able to legitimately compete on the commodity market, but it would be interesting if you could use your money to buy / sell company stock to either help or hinder the active players (and possibly set a final ranking). Hopefully this would give a 'jury of peers' survivor mentality where screwing someone over may also lead to your buyout cash going straight into your opponent's stock.   

30 minutes are good for a quick game, are there plans to make the possibility for an epic game that could last for 6+ hour or more depending on how you play the game?

Is this game going to be 64 bit only?

Even though doesn't appear to be a graphic pressing game, will this be using mantel?

Should the game do well is there plans for any future DLC's or Expansions and if so would the founders get any type of discount on them?  There is no mention of such?
