Now there’s the old dirt cheap option which is still working.

    I’ve drawn countless fantasy maps by hand while computers were just an expensive not so convenient stuff (yeah, fantasy, I used to GM fantasy, like everybody ;P ).

    A pen and a paper are the most cost effective way to keep an eye on your world your character’s travels and so on without spending much money (for now). 🙂

    I’ve been there, that’s how I designed my original maps afterall. ^_^
