Foil to game theory in politics:
1. The commensurability of goods in terms of utility when preferences are context dependent, including interpersonal, inter-good, and inter-situational utility
2. Computational complexity of changing utility function in each round, which is a function of utility over distributed probabilities
3. Uncertainty
4. Is action by definition utility-maximising, or is utility something which is maximized by action? If the former, see 1, if the latter, how do we know that this concept of utility is commensurable with all goods across different contexts?
That is partly why we apply game theory models by analogy, when the situations are stable and the institutional context, values, preferences and payoff functions do not change too much over rounds.
