I love this game. On Classic Korg, I have added 1 item and one rule to help me play World Mode: Complete All Locations, which I have yet to do. I've gotten close a couple of times.
The item is Bracers armor (10GP), and it allows my character to win if my d6 roll matches their X value, rather than lose a tie.
Bonus Rule: After each Location is complete, I roll 1d6 to keep each wearable item, 1-4 and the item is scrapped (or pay 1d6 in GP to repair and keep) and 5-6: I keep it for the next location.
