Opinion: Populaiton
I dislike how the population mechanic has been simplified down to citizens. Their existence is cool and fun, but serving as the proxy and replacement for population is not something I enjoy. Having the option of multiple species is interesting, but doesn’t really provide much and usually has a drag down effect on happiness.
Anyone else think that the population system in 2/3 is better than 4? I do like the colony system a bit more, though it can be a bit silly depending how far away colonies are from their hub world.
