Currently I am detailing the maps of Secret of Evermore, by putting the location of alchemy ingredients on the map. No more having to put up with the dog wandering off for a scratch or worse, a yawn, no more "dead trails" where the dog leads you along, then stops because the path algo can't reach the ingredient, and no more having to guess where the ingredient really is.
A small setback though: The ingredient quantities are in sets/randomized/etc, they're just not the same every map entry, so I've got to re-do Prehistoria and just list the alchemy ingredient in the spot, I had been putting quantities, but it's just not accurate.
I'm also slightly concerned as to how I'm going to expand the Mad Monk Merchant's details in Crustacia, since he sells more than just the Chocobo Egg in additional purchases from him, and there is a way to make him come back. I might just write in the white.
Also the OP of the maps seems to have captured Ebon Keep before Ivor Tower's Destruction, but not after, when the town opens up.
