What's missing is a way for the game to enforce your predictions, rewarding you when you get them right and punishing you when you get them wrong. It would have a quota of ~7 moneys and you would need to choose 1-3 sites that will have that amount at the end of the round.
Once that is working you could get into more involved simulations stuff. Like if every site had a unique resource only they could produce, which I thought about but didn't know how to implement.
