No TL, but the unique aspect of this world is that the various different civilizations in general achieved own tech development and resisted quite successfully to any colonization attempt. Only about a third of the American continentand a 10% of Africa are colonies or colony-heir states; even Australia has three independent aboriginal entities (Darwin/Arnhem land, Southeast, Tasmania).
Britain is fully Celtic and has Celticized vast areas of North America together with its rival Scottia (Ireland+Scotland). Japan has an impressive empire across the Pacific, possessing the Philippines, Sakhalin, 90% of Papua New Guinea and Queensland, the extreme Siberian northeast and a vast stretch of Western North America from Alaska (Arasuka) to OTL Oregon.
All in all, is a very equilibrated world.
I'll post a brief description of every state/territory when I find the time, maybe tomorrow (here its almost midnight).
