The main problem is that it looks (from the shape of the continents) like a Hobo-Dyer or maybe a Gall-Peters, but the Lat/long lines look like they were lifted from an equirectangular. of course, it could still be accurate, but the continents would be a bit extremely shaped. for a pod summary of maps, see this interesting chart.

Could you provide a description of the tech levels and maybe some major historical events in this world?
