I wouldn't mind having markers for some of the official modules, if not fan-made ones, just so GMs have a bit of an idea how close, or how far apart, the various adventures are, so they can put some thought into adventure selections based on where they're basing their campaign.
So what I ended up doing, which I think is pretty cool, is listing Faerun modules in a table that you can filter by PC level, edition etc and then it has a link that takes you do the big interactive map, and zooms in to that spot.
its going to take a few weeks to enter all the modules, as I only have so much free time, but its going to be pretty cool when done. I might even make $1 or $2 on affiliate links this year.
As I map out the Matzica modules, I'm thinking that is a rather unfortunately designed continent, and doing some research Ed thought that too.
Perhaps we need a Candlekeep task force to redesign the continents that are too close to world history. I suspect WOTC will ignore the problem for the next decade. We should clean it up while Ed is still around.
