First off, no problems installing it or loading it to play. So far I've noticed that the processing of turns is taking considerably longer than the original game. Maybe 3-5 times longer? The initial turn took over 2 minutes and now they're running 15-20 seconds from the time you hit enter until you can do anything again. I don't remember it taking that long in 3920BC before. Maybe it's doing more calculations? I have no idea. I noticed that the tech is about double right of the bat. Is it double throughout the entire mod or does it triple or quadruple later on when the research tends to accelerate too much? Back to playing. Thanks for the improvements.
