On the original topic of the thread...
I stand by my choice of China with time victory. Just look at the way scoring is calculated which is basically...
population score = 5000*civ pop/world pop
land score = 2000*civ land/world land
technology score = 2000*civ tech/world tech
wonders score = 1000*civ wonders/world wonders
The first two (pop/land) are easy to quantify using the following resources

Note: I used 150m sq km for total land area.
Using the top 5 largest and top 5 most populous countries:
China:
pop score 5000*1.31/6.4 = 1023
land score 2000*9.6/150 = 128
For a subtotal of 1151
India:
pop score 5000*1.08/6.4 = 844
land score 2000*3.3/150 = 44
For a subtotal of 888
USA:
pop score 5000*0.30/6.4 = 234
land score 2000*9.6/150 = 128
For a subtotal of 362
Russia:
pop score 5000*0.14/6.4 = 109
land score 2000*17.1/150 = 228
For a subtotal of 337
Brazil:
pop score 5000*0.19/6.4 = 148
land score 2000*8.5/150 = 113
For a subtotal of 261
Indonesia
pop score 5000*0.24/6.4 = 188
land score 2000*1.9/150 = 25
For a subtotal of 213
Canada
pop score 5000*0.03/6.4 = 25
land score 2000*10/150 = 133
For a subtotal of 158
So in table form the top five from pop and land are
China 1151
India 888
US 362
Russia 337
Brazil 261
In the real world the nature of technology sharing means that maintaining a sizeable tech lead is tough and most will score close to the max 2000 on this one.
Also, in the real world, wonders (even if the definition of them is highly subjective) are clearly spread around the world with no country holding a significant monopoly.
These facts taken together mean that the chance of anyone overhauling China and India as the one-two on score is extremely remote.
Of course some will argue that other victory conditions have already been achieved, but I just don't see it.
