I work on things. You’ll find a lot of the results at my website.
To do something like this without a lot of manual labor, you’d need a database of images, which I don’t think exists. But if you already know which files go where, it’s not quite what you’re looking for, but I used to use Ant Renamer when I spent a lot of time on Windows.
The game that I probably go back to the most frequently is Cataclysm: Dark Days Ahead. While it looks like any other roguelike on one level, it has a bunch of different interacting systems, story elements scattered around (if you only find one cataclysm, then you’re not looking hard enough), and has a debugging system that (if you’re not interested in the action-oriented aspects) can be used to cheat and turn the game into exploring the randomly generated world.
While it doesn’t have the features itself, you might want to check the Watchy page, because it has a clean comparison table of what I imagine are the major contenders. Bangle looks like the only one with GPS, out of them.
