My Hopes for the new year:
Fix the pacing for the ages, since the building production nerf, I've found ages seem to be racing by too quickly, I'm hoping for a pace that lets you ease in and enjoy your time in each age.
Crisis overhaul, I wish there were defined routs to better mitigate or overcome a crisis, and on the flip side, a way to absolutely get destroyed by one, I'd like the crisis to come to an end before the end of the age, have you either picking up the pieces before the transition, or gloating over how well you handled it. I'd like actional traditions based on the outcome of the crisis, think Golden/Dark age bonuses from CivVI
Rebalance of influence. There are too many things to spend it on and not enough yield, opportunity decisions should be, which sanctions, which espionage to partake in, not weather I should engage at all. I'm only spending influence on IP and endeavors.
I'd rather a new yield, or a rebalancing to the benefits of spending it in other ways.
I actually think of all the things in the game, influence is one of the better paced ones (sort of). It doesn't grow exponentially, and you do often fight for it.
The biggest part I find lacking is that once the IP race in the age is done, you lose a major use for it. Like for me, I would say in a typical game, I'm struggling through antiquity, exploration I spend about half the age where I am using it up as fast as I get it. And then the second half of exploration I just have nothing to do with it. Especially if I happen to have a setup with hub towns which can give 10 or 15 influence per town, there's times I'm absolutely rolling in it. I do think sanctions and espionage are a little hit or miss to understand - like sometimes I just feel like I'm blowing influence into the air for no reason, other times I'm spending like 120 influence and getting a burst of 3000 science from it.
But yeah, definitely the ages need some pacing. Antiquity is good - more recently I don't find myself with nothing to do, I'm usually trying to get those last items in. Exploration is a joke - my last game I finished it on turn 76, meaning I reached 95% by turn 66. There's just not nearly enough time to solidify yourself, set up your engine, and use it, before time runs out.
And yeah, crisis definitely need some balance to them too. Like in this exploration era, things rushed by so quickly that I never even reached the 3rd stage of the crisis. And you just end up with such an imbalance. Sometimes the crisis is something you have to care about. Other times I pick a policy card that's worth like -6 happiness to a couple cities in my empire that are normally at +50, which means it's nothing to me.
