One thing i noticed on your first videos is that you didnt build monuments for the culture pop. You used libraries instead. Is this what you always do or was its just a circumstantial type of thing. I usually tech mysticism if not creative for the added culture. A monument only requires 1 population, and usually you have at least one food resource per city so whipping is quite easy. This is usually quite important for culture wars later IMO. Unless you get a wonder (which is hard on emperor without a strategic resource\without the industrioyus trait) then culture can bve a significant problem, especially from a creative civ. If you think about it, a monument adds 50% of culture to your city (assuming you build libraries). On a pangea map you are bound to have border problems with another civ who is your ally, so culture is the only way of combatting them.
I think roading would have been a better option than mining the hill. Seeming as you have no rivers (or very few), and roosevelt came from the east, you will need to expand in that direction neways, so roading to that effect would make sense. Also, like i said in the comments section on youtube (flobbing donkey), the health bonus is not important for your capital, but it can be VERY important for your second, third or fourth city (of which location you do not know at this point). If that city is slap bang in the middle of a jungle then it needs the +2 health in order to not have unhealthiness and produce a unit/worker quicker.
Im not too sure about the value of an early wonder. I spose the great wall is a possibility. But in my experience of pangea on emperor is that you dont often need it because the AI expands very quickly and kills off the chances of barbs spawning. Also, a great spy is probably the worst early great person you can pop, unless you are going for an espionage based economy/tech strategy, but this is usually quite ineffective IMO, and highly circumstantial.
As for BUG, i think you should use it. It doesnt really aid you in any great way, it just allows you to not do things like check on cities/foreign advisor for curcial information. Its not so important in your early walkthroughs, but for your mid to late game ones id definately reccommend. It would allow you to talk/show more of the game without doing pointless crap like check to see when you can whip.
Great series though. Im really enjoying them. Kepp it up.
