Map Work In Progress: Which Way to Go?

I actually have about five different projects in process that I'm skipping back and forth between. Some of this is due to a couple being larger projects (which need more resources than I currently have available) and some is because I haven't quite figured out the end-game (pardon the pun) for these efforts.

When I was cleaning out my desk a couple weeks ago I came across a couple game world maps I had created twenty years ago. At the time I had found what I thought was a cool RPG resource and I was in the process of translating it into my own campaign world. IIRC the "resource" was a book detailing a number of cities and countries that some series of choose-your-own-adventures books was set in. What really intrigued me was that each entry was quite abbreviated and no more than a page per country. Really just the highlights, but with just enough crunch to satisfy. In many ways I think this early exposure is why I liked the Garweeze Wurld Gazetteer from Kenzer & Company (now bundled with the Atlas to form the World of Aldrazar)

Anyway I found these old maps and some were heavily marked up on tiny hex paper and others were relatively unused. Sine I no longer have that earlier reference material I just tossed out most of the maps and scanned in the best copy I had left. While I have some memories of working on those other maps, the nostalgia didn't outweigh my desire for a cleaned out file-cabinet desk drawer.

My immediate question is what to do with this map now. Obviously I'm going to share it, but how much work do I want to put into it? Do I want to just update the map....do I want to start another game world guide with it? I'm half tempted to make the map the best I can (within reason) and then start to "drill-down" in a series of small products. If I did so I'd obviously want to leave everything a bit fast and loose so enterprising GMs can work their own particular magic.

Do I want to write to a specific game system? I'm starting to come around to maybe using Labyrinth Lord as my default "OSR" stand-in, but really I'd prefer to make it as usable as possible. Of course I really have to have fun doing this however I do it because I'm going forward with the assumption that very few would be interested.....unless I made everything completely free and then most who express interest would just download it and barely look at it.

At any rate, I'm of the opinion that I'll take this base map and start working on it, releasing the tweaks as I go along.
