I actually find the Italian version more similar to the PBS original, with its own back room for various sketches as well as the option to pick "Where do you wanna go?" if you beat the map round. The only thing that was different was that the order towards capturing the henchman didn't necessarily have to be loot/warrant/crook like on most other adaptions. If the show got picked up for a sixth season instead of changing itself to "Where In Time?", I'd wish they'd do a special around the world episode/week showcasing the various international versions where chiefs could help the Gumshoes with catching Carmen, but I'd make that a primetime special due to its higher profile.
Still, Africa and "Australasia" are certainly no easy feat to accomplish, despite New Zealand being in the same region that its map round would be played for. Even adults would struggle due to the tiny size of all those islands.
