I'd love it if we could post a bunch of different medias (games, tv, movies, books) that we think could be transposed very well to a game Guided by Firelights.

I'll start: God of War

I do feel like a bunch of adventure games would work fantastically with this system, but I'm intrigued by this one in particular. There are huge boss battles, cool items and armors, and the idea of having a companion would be such an interesting thing to experiment with.

You turn!

Tomb Raider/Indiana Jones

Exploring ancient, crumbling ruins, full of traps and danger. This could work well as a "push your luck" game, where it's harder to heal and you're more seeing how many treasures(beacons) you can acquire before you escape or perish.

Jurassic Park

Abandoned structures, broken cages, dense jungles, and forgotten roads. The beacons could be generators, radio towers, etc - a mechanic where you had to visit them in a certain order might be good here, where you get parts from an equipment shed, restore the power, radio for help, repair a vehicle, and so on.

Your encounters would be dinosaurs, of course, possibly ranked by size/deadliness. A pack of raptors would be equivalent to a T-Rex, stuff like that.

Resident Evil 

An old vila (and there is more than that :)) with hidden paths where had to find clues to go on.

There boss fights too and also you have to search for "treasures" in some way or another. 

Supernatural

Run from city to city to find that demon who done baaaad things. 
The beacons here: 6 things you need to kill that demon
On that way: some of his henchmen
