I do think my crash is due to my computer/gpu sucking cuz I got around turn 130 before I crashed out when I played on Large instead of Huge. The other settings were emperor, standard, pangaea, 8 civs, 12 CS.
Demographics
At the end, I was ranked second in crop yield, production, and gnp, sixth in population (the biggest more than double me), eigth in soldiers, and first in literacy (even though ai got to the new eras much faster than I did). My stats were pretty good only because I had a lot of land to expand into; otherwise, I would just be middle of the pack.
Gold
My gpt was pretty low throughout. I only went into the currency tree when I felt I needed to boost my coffers. I had just reached early Renaissance when the bonuses from markets, abbeys, and trade routes stopped being enough to keep my in the black. I was just about to build the town hall (or house, don't remember) when the game crashed. With the money I was making, I was able to field a relatively small elite force of units. Everything was spaced out well; it was easy enough to keep myself in the black, and if I really wanted to go for the gold, I would have had to sacrifice some more important techs.
There were a few inconsistencies in the gold benefits though:
-ruins give 70-100 gold
-barb huts give 25 gold
-I didn't have fishing boats show up on non-resource tiles
Science
Techs still came by a little fast but now I'm starting to think that's a relatively good thing; there are a lot of techs now. Still, I was blitzing through a lot of techs in less than four turns. One effect of splitting the techs out is that it couldn't be sure what "tier" I was in anymore, so I don't know if I was blitzing through old techs or more modern ones. I think a standard of ~6 turns per techs would be a good pace.
I actually found myself specializing in one or two branches, something that I have never had to do. However, it can be a little bothersome to check through all the branches to see what's available; sometime in the future, can you compile a completed tech tree for reference?
And a litlle request: distinguish for the player whether or not a tech is "dead-end." It wouldn't make any sense to grab an engineering tech that doesn't lead anywhere if I was focusing on science.
Production
I was really surprise in a previous game when another civ declared on me
and actually had an army!! I lost two cities before I could throw my Legions up to the front. Very intense...
This game I think I caught my opponent off-guard. I managed to take two of her cities without much resistance and I was gearing up for a third before the game crashed.
Culture/Government
I think the culture threshold is a little too high. I was getting a new one every ten turns (with the help of a few select wonders). When you add in the different policies, that pace will be a little too slow. I think the pace is good for the governments cuz you don't want people blowing through them, but the others need to be sped up. Or I could see a system where you get a "policy" in each group (government, religion, etc) working out pretty well.
In terms of the governments, I find I spend most of my time in Republic for the empire building effects. However, I was
sorely tempted to switch to Democracy to enjoy fast growth. +30 food for farms/fishing boats

? Again, I was posed with a problem, and either solution had benefits over the other. Great stuff!
That's all I remember off the top of my head. Overall it was a very enjoyable game

. Too bad it had to end so soon...
