Some general observations:
Unfortunately, the tech pace hasn't really changed. We got rid of outliers with chop overflow abuse but in the end Magnus dominates even as Mali. There is still no reason to leave resources. Though you may consider keeping jungles to keep droughts away. Pingala might actually make matters worse. I dunno why they even buffed him so hard in the first place.
The AI is pretty poor as always. They're really struggling with the resource system.
The resource system is pretty unpleasant and I spawned with only niter. Infantry requiring oil is a slap i the face too.
Power is sorta irrelevant thanks to the above, and I didn't really pay much attention to it. T3 buildings are still w/e.
Random disasters are really cool and aren't too intrusive. It's good to force you to pay attention.
The UI is still bad. Notifications are still garbage, but we have a queue, but it takes so many clicks.
The World Congress is excellent. Voting in to increase the production cost of military units was awesome as Mali, since I just buy units anyways.
Diplomatic victory, however, is not. In fact, it's pretty useless because you need to wait 30 turns between votes, with the exception of a wonder and some events. I had it at 8/10 but it would have taken 20 turns either way. Scaling needs to be better. Also, your own allies vote against you which really sucks; the only reason why they failed is I had way too much favor to block out all their votes. They did vote to make writing give more tourism, which accelerated my culture victory though.
Upgrading units from gold is still too effective.
Grievances are a much better and transparent system over warmongering.
Mali is pretty good, but rather terrain dependent.
Rock bands are annoying due to the high RNG factor. The other fact is I would have been better off killing off France/Cree instead of doing this stuff, so.... Concept overall is creative, but please remove the scaling cost.
Overall, it looks fun, and the disasters are implemented quite well, making the game much less montonous. But balance remains an issue and early game really hasn't changed.
