I've been considering a few changes to gameplay (they probably might not go into effect until next game):
Objective (policy) points are "banked" every 2 years, at which time policies are reset to 0.
Policies are completely re-randomized every 2 years.
Optional: Any player with a negative score (either for the 2 year period or net score, TBD) at a 2 year mark is removed from the game--last one standing wins.
None of this is necessary, and the re-randomization one would completely destroy the gameplay.
This would prevent a few people from making an alliance that would last the whole game, as well the game more interesting.
I think it'd actually make it incredibly less interesting, since it'd be entirely devoid of the same level of strategy in play here.
I understand we're making this look easy, but it took a considerable amount of effort and trust for those in the SRP to organize an alliance without revealing the entirety of our policies to one another, to come together and actually cooperate on some level, and to negotiate policies we would support for others when we don't have them ourselves. Also keep in mind that regardless of how many people ally, only one person can win, so in reality everyone is still out for themselves.
Payne is complaining about the game mechanics because he's on the losing end of a winning strategy, that's all. He is fully capable of forming an alliance himself, or cooperating with the controlling party to be screwed as little as possible. This is how actual politics works in real life, and the fact you've replicated that dynamic in a forum game is impressive to me. Don't ruin it in the future with knee-jerk rule changes. Any updates not designed to preserve that dynamic are unnecessary, and those seeking to prevent it are extremely counterproductive.
The fact that forming a political party was done out of strategic merit, rather than simply being in theme, speaks volumes by itself about the current state of your game.
At any rate, the alliances will already be tested at the four-year mark when additional policies become available and negative policies are introduced (as I am assuming they will be). That will also be an opportunity for another party to overtake the current one to regain points lost this term, if they actually take the time to employ proper tactics.
One change I would recommend in the future though, is the part about "all new policies will be either positive or negative", to instead make it so they can be a mixture of positive and negative, but everyone receives the same mixture of them (so if one person gets +2, +4, -4 policies, then everyone got +2, +4, and -4).
Anyways, keep up the good work, this has turned out pretty well so far.
