I'm making a map of my fictional world, and I would like it to be as accurate as possible, while still being in my (nonexistent) budget. Any recommendations for any kind of map making medium would be greatly appreciated. I'm looking for something more advanced than just paint.net, and maybe something that would allow me to edit a globe, however the ladder may be expensive.
I don't know if I may be late but I suggest InKarnate. It is free and you can make some really great stuff even if you can't draw for shit. I have been using it for ages and it has served me well.
