I 100% agree with that breakdown. But I disagree that the game perspective "matches the market".
The beauty of the marketplace is that there are all types of people in the sandbox: fundamentals, macro, hedgers, short-sellers, punters, high-frequency traders, mean-reverters, money managers, pension plan managers. And all of these people have slightly different time horizons ranging from microseconds to years.
The market concept is this beautiful thing that supports all these people: aided by strong regulation, strong oversight, and better technology.
One could say marketplace is a category of game field where the rules and objectives are different for many participants. I want to sell my apples for the maximum possible profit today; she wants to sell both her apples at max profit and lettuce at max speed within its shelf life; the customer wants a decent lunch. Different measures for success, different time limits, different strategies in the common marketplace.
