Are you supposed to build wide in these games?
I'm not really sure, because the vassal system seems only partially worth it. I mean, it's better to have them than
not, but looking at the numbers of per turn income, it's fractions of fractions. The amount of tribute they give each turn is fairly small, and what really confuses me is how you can't manually build any improvements in their territory for resources or have them send those resources to a city (at least as far as I could tell.) It seems like that would make perfect sense for a minor settlement versus your main cities, but instead you're stuck relying on the AI to build up
all of your towns, rather than just an optional governor system, which feels extremely backwards. It's not exactly micromanagement to choose what a city should build over the next 10 turns.
I went kingdom in one game and imperial in the other, and the latter seemed better to me, allowing you to turn your capital into a tall powerhouse. Turning multiple vassals into regions really saps the hell out of your culture production, which I guess is the main limit (the unrest penalty is a joke), so if you're focusing on lots of temples or whatever, I guess wide would be more viable.
Warfare also feels
very punishing, since not only do you deal with the increasing unrest in every settlement every turn, but taking a city effectively ruins it (halved pop and every improvement destroyed, along with militia having to rebuild),
and gives you a bunch of chaos. Which isn't just a one time increase, due to how the system treats every increase as a boost in number immediately
and per turn. (Thinking about it, I do wonder if it would be possible to effectively ruin an opponent's country by being in perpetual war with them so they had to keep dealing with the unrest and posting guards, so long as you can manage your own more efficiently.)
Some of the chaos stuff just feels totally untested and unbalanced, too. One event has groups of barbarians spawn for
every region for
every player. Another has a mild increase in unrest or a small decrease in food. Fun fact: if you go Khan as an ideal and make all barbarians non-hostile, then the chaos events that spawn them won't have them rush at your cities or raze your stuff. But their presence still increases unrest and acts as besieging your towns if they get adjacent! So I got to spend like 20 turns slowly mopping them all up because instead of suiciding on my walls, they just sat their making all my regions 80% efficient. I guess you could use that as a way to train your troops.
