Studio Ghibli's 'Kiki's Delivery Service' as an open-world game whereupon you actually hop on your broomstick and have to deliver parcels to individuals across the village where she lives. Think a 'crazy taxi' RPG where you fly to deliver parcels instead of passengers. You would have to deal with issues like weather conditions, weight vs. travel time; and occasionally race against competing witches. It's honestly a 'take my money' situation - I've considered doing it as a fan game, but I would need a small team, and of course we wouldn't be able to profit from it. I'd ultimately love to see it adopted into even a mobile game.
