My first published map, Janxerix started as my in-editor playground, testing how to use different surfaces and finding creative methods of using things, but turned into a highly interactive mixed map with slight RPG vibes in that the optimal line isn't obvious - if there even is one at all! How the start of the map gets driven changes how later stages of the map get approached, and the techturns are driveable both with and without slides, testing the driver's reactivity.
This isn't exactly the most consistent map on the Exchange, but I can at the very least promise that there is fun to be had!
