So, I've played three games now, and I'm continuing to learn a lot. My third game has been a massive success by all measures, instead of expanding, I decided to conquer my early empire, completely taking over Spain and the Kongo to gain an entire major continent to myself, and eventually expanding to 13 cities before I stopped creating more. I currently have about 450 science per turn, when my closest competitor is at 150. Production times for districts are still pretty ridiculous despite a million industrial zones, but I have such a large lead anyway, maybe its justified? While warmongering penalties are high, I think conquering is more rewarding than it was in V. Ammenities are an issue, but war weariness only lasts when you're at war from my experience, or at least, peace can drop it down. Even if the AI doesn't place cities optimally, growing a city from 1 pop is substantially harder in VI because of a lack of food buildings, and population loss is less for taking a city. Conquering a suboptimal location is better than razing it, in my opinion. Going wide lets you get a lot of ammenities, and if you can conquer your own continent, some other benefits pop up. In my first two games I was struggling to compete with the AI for suzerin of city states, but with my own continent, I was suzerin of 4 with minimal effort. One of these let me get massive culture boosts for trade routes with city states, so all of my trade routes gave me +9 culture for a while, and as Norway, I was able to explore to the other continent immediately after I finished my conquering, giving me no warmonger penalty with the remaining civs, and a fairly large boost through trade. So, the warmongering penalty is high, but don't let that stop you. Armies are cheaper in VI than in V, and if you can pay for your army, you can conquer, and you can snowball. Conscription is a great policy. So, for my second point, the great person system doesn't work as its currently implemented. In my second game, I was spain, and way behind in technology. However, I had four encampments due to invasions, so I was getting a lot of great general points. I ended up getting the last two great generals, so I could... get a bonus towards atomic and information era units. Great... I had field cannons and conquistadors at the time... In my third game, I'm currently way ahead in technology, and I'm getting 40 great engineer points per turn, while England, the next best civ, is getting... 3. Well, I'm trying to go for the space race, but since nobody else is getting engineers, I'm kind of forced to get them all, including the ones that give +appeal. Ideally I'd want to skip these engineers, but it's actually just faster for me to burn through them, because I'm basically guaranteed of getting them all. Considering how useful the last great engineers are in the space race, I'm just focusing all of my cities on getting great engineer points right now or building spaceship parts, and I've gotten through two useless atomic engineers while waiting for the ones I want to come up. It's kind of stupid. The great person race works if the game is close, but doesn't work if there's a tech gap between civilizations, because their effects are so regional. If you're behind but ahead in one area, you get useless great people. If you're way ahead in one area you have no choice but to get useless great people. This system needs to be redesigned. Also, as a side note, since I had a continent to myself, I didn't need to get a military beyond my initial horseman rush. Therefore, I got the technology to upgrade my horsemen after I got the technology to create a martian colony. That's... kind of messed up.
