Comment about the ingame government balance:
Socialism is OP in this game. It turns this game into a critter breeding game. Always aim for it first, the other 2 types of economy are completely useless.
Suppose you have 2 parent cards, A and B, then use them to breed C. Put C in that representative to boost A and B, then discard C after an empty draw. Rinse and repeat. This is exponential growth until it hits the 999 hardcap. It should be able to reach all 999 stats with around 150~200 turns.
For political system, totalitarianism is the most useful. With it, you can increase influence of a card from 1 to 2 in academia, then reduce to 0. This allows you to reduce influence production of everything to 0, greatly easing management.
None of the 3 tribal systems are important. Caste system could be useful if you have "Workplace shift" prestige upgrade.
