Haven't heard of it, but i checked it out after your suggestion. Looks very interesting, thank you! I agree, especially for a procedural generation the combination and variation of pre made areas might be interesting. El Dorado also has varied costs for traversing tiles - a mechanic i initially planned, but scrapped because it would work a bit strange with the caravan. Now that i think of it, maybe the movement across some special tiles could require an extra food or ore. That's why it's good to look for inspriation, so thank you for suggesting it :)
