This depends on how much Automation immersion you wish to achieve i.e. whether you also want to divide the world into Gasmea, Archana and Fruinia, or whether you want to model a specific market in the real world instead (the beauty of not having these things more rigidly defined).
For example Rk38 is currently using my price estimator from the CSR round that you won, in the current round of the CSR. Why? It works surprisingly well across multiple markets... specific to Australia.
The downside of that of course is that everybody has to think very hard about how to model their own pricing etc. as a function of ET and PU and material costs.
ALTERNATIVELY, why not set up specific competitions with scenarios in campaign mode? Koolkei did this, I think, with a WWYD type scenario. It's not that difficult to say: you are a such and such sized company in this and this stage with this and this much money and your job is now to do such and such a model for this and that. Trouble with this: 1) you can only achieve limited scenarios without having to do significant playthrough of your own to export a company file if, for example, you wanted your company to be established in more than one region 2) you're locked to the 3 region map 3) you can't then just tell people to go and play through the next decade themselves as the markets may then behave differently for each player which wouldn't be fair.
