I think Stardust could end up being a great way to bring new players into the game, and old players that have walked away might return, if an internal market is created. The ability to buy and sell things like Coal would create incentive for small players who have just begun playing, or who are being farmed, to at least have a reason to continue participating in the game. Of course, ideas are one thing, and programming and coding are another matter. It's easy to come up with new insights, so I won't say more than that - an internal market to trade Stardust for everything from Coal to Planets would make NextColony more attractive, in my opinion!
