Thanks
The landscape will be extremely diverse, there will be hot sands in Arabia, fertile plains in Hungary, swamps and woods in Rus, cold woods in northern Siberia, fertile steppes near Black Sea, dry steppe in Iran, high mountains in Himalaya, Caucas, Tien Shan, Altai, lakes in Dzungaria and southern Siberia, oasis in Turkiestan, Khorasan and Uighuria, fertile river vallays of Syr-Darya, Amu-Darya, Indus, Tigris, Euphrates, Nile ... and many many more nice lands

I think that small percentage of Seas is good as all the nice action is taking place on land anyway. Also still there will be quite a few navigable reservoirs (Black Sea, Mediterranean Sea, Red Sea, Persian Gulf, Caspian Sea and probably even Aral Sea and Balklash lake will be navigable, though will host only low tier ship) and it will be possible to sail from Crimean Peninsula to Nile delta.
I really count on you mate
