The soundtrack is, if you haven't heard it, utterly amazing. I highly recommend it: https://www.youtube.com/watch?v=giqNtBAukbg
edit: I'll also note that "economic RTS" doesn't quite do justice to Offworld Trading Company - it's a real time strategy game, but the only warfare and combat is economic. You place structures which mine resources: water, iron, carbon, and so on. These resources can be purchased and sold on the open market, or you can refine them into more advanced resources (which requires having the structure to refine them) and sell the advanced resources for a larger profit.
But of course, the price of resources will constantly fluctuate based on supply and demand. Do you need to sell glass to make a profit, or can you just sell silicon to the person who wants to make glass? If your opponent has gone all in on producing steel, why not just buy all the iron on the market, corner the supply, and sell it back when the price goes up?
(While you're at it make sure you disable the enhanced espionage mechanics, for better gameplay. But that may be just opinion!)

In all fairness I feel like there is a core of a very interesting mechanic there. It just doesn't gel with the fun stuff that is the rest of thr game.
And don't get me started on spawning a Great Spy instead of a Great Engineer or Scientist...

Is Civilization IV going to change? I'll welcome any update that fixes this

And so close to the original. As an appreciator of good composition, the goosebumps with this had me sold and feel lucky to be alive!
