Well, I think that a general map could be nice. No, "[The Woods] take up so many units of measurement and are composed primarily of some horribly unnatural form of tree, due to some crazy magic. There are some pines, as well." or, "[The Zone Of Many Colors] has so many blocks and contains [Random Shop], [Awesome Hairdressers], and [The Lost City Of Atlantis]."

More of a, "Yeah, so, this place is east of this place, this place is about twice the size of this place, but there'd still be plenty of space in both places to chuck skyscrapers at each other, if you really want to."

It could be useful for those who like to have a better idea of where they are. Nothing will be stopping those who just want to go straight to Trog's, for instance. Yay for not role-playing that you're walking down every street, if you don't want to. Time skips are sometimes desired, but not all the time.
