I enjoyed playing this game, but I have seen the possibility of creating a resource-based economy, rather than just a post-capitalist society. Such an economy would use the scientific method to solve problems, without the constraints of left and right politics, money, poverty, and war. It would require completely different societal dynamics, and I think The Venus Project has some interesting ideas on this topic.
Update: I diverged from TVP and decided to make Humanist Socialism.
