Nice mod,
Played a large map, 14 civs, snaky continents, your custom game speed. I played noble. The AI is just so bad when it comes to research if tech trading is off. Some AI Civs are still researching alphabet when i am completing railroads. Can u implement a tech diffusion component? Help the AI with research when tech trading is disabled.
As for your custom game speed, it seems good. Needs a little tweaking. Lower the time it takes for buildings by about 25 - 35%. It seems that some buildings take more time to build than it did to research the tech needed to build them. (Granary comes to mind). Unit production should also be lowered by about 20 - 30%. I would leave the tech rate where it is. I checked the xml to see if i could tweak it a little, and do some playtesting but I cant find the entries for your custom speed. What file is it in? Or is it under a diff. name? I noticed to marathons in 1 xml is it one of those.
I played version 1.2 as Stalin and some unique units didn't work properly. I think it was SU-85 tank, and 1 other. You can't attack with them. Also a weird bug with fighters. For some reason i could only attack with 1 or 2 in a stack of 5 - 6. The outline of where they could attack didn't show for these. Don't know if they could intercept.. no ai had fighters at the time.
You prob. didn't implement this yet, but if not some wonder movies don't show. Could use an interface button that magically makes a hot chick appear.
Other than that it is a good mod.
