Disappointing
1) “The Political Machine has an issue-driven model rather than a poll-driven model. Depending on what issues matters at the time of the snapshot, different candidates have different advantages.”; It should be both, because the political advantage that a candidate has can erode over time, and new issues can arise giving way to changing advantages for candidates. Also populations and social norms change which gear up certain political bases or interest groups.
2) “The model has an error factor of around +/- 3% and it cannot take into account with great precision the effect of advertisements, endorsements, speeches, TV interviews.” What! This is the base of a political campaign. Politics is perception. How the public perceives your candidate is everything in a campaign, not to mention, the media plays a very large part in shaping issues.
I have more, but in the interest of time and the fact that I am not here to teach political theory, or public administration, I will save it. The game is a good first try, but I will buy when it has all the good stuff.
