One frustrating thing about the government plaza is that state workforce is boosted by building a district. Early game, I really want to avoid building districts but getting one for that eureka is often worth it. Ironically the gov't plaza would be an ideal one to build to get that Eureka as it gives multiple options to help with early expansion if it wasn't locked away behind it :/
I think changing that Eureka to something else would open up a few different early game openings and be quite a positive change.
I think that's part of the struggle. It kind of forces you to chase an early district or delay your cultural progress. Same reason why you need the pop count inspiration before you get the +50% settlers policy card.
As for the government plaza, I tend to delay it too often, I think. I need to start valuing it more for the governor slot, which is often going to be another promotion on Pingala, meaning it's worth probably 5 or 6 science/culture per turn, and so is actually better for science/culture even than a campus or theatre. But yeah, it's a bit expensive, so you need it in a fairly strong production city.
Build it quickly, even in a subpar location; those promotions and buildings are too useful to delay.
Ideally you want to build towards the center of all your cities so more districts can be next to it.
Yeah in either the second or third ring if you can manage.
Playing deity, sure it gets crowded and is is of less value. If you are not going to settle more, not going to war much and have enough governors then there is no point? It does cost a fair r amount of production and cannot be bought with gold.I'm curious to hear people's opinion on Ancestral Hall. By the time I build government plaza there usually isn't that much land left to settle. (I usually play standard maps). Am I just building government plaza too late or is my experience common?
