If Firaxis could make an ordinance "tree" that grew and changed with the passage of time and changing scientific and cultural values that would be brilliant. Particularly if the effects of differing combinations of ordinances were not felt immediately but built up over time. That would actually lead to the sort of situations we have had in the real world, with badly chosen or antiquated policies slowly fuelling resentment until one final straw suddenly explodes into revolt, repression or emigration. This would help to banish the eternal China syndrome, one of Firaxis' stated ambitions. Getting it right would make designing the perfect tech tree look easy, of course
