Albatross!
The campaign in heavy in exploration, problem-solving and NPC interaction, and light on combat.
The PC:s are an elven princess and a fairy from the Magic Kingdom, who have found themselves employed as maids in modern Anime Japan.
Right now my party's theater group has been kidnapped by captain Nemo, and forced to drive electrical steam-punk worker mechas at the bottom of a deep sea trench, where he is excavating the ancient city of Mu. What he does not yet know, is that the players have managed to interface with the city's holistic crystal-driven virtual reality system...
Previously they've managed to foil the takeover of the Japanese gods' and spirits' favourite bath house (see "Spirited Away") by cthuluid tentacular horrors from beyond space and time, and return it to the nine-tailed kitsune who was the rightful owner, as well as solve a kidnapping case involving yakuza mermaids and travel 15 year into the future to save the city from invading transdimensional frogs with rayguns, etc.. etc...
So that's what you get when you order your pizza with the "special" mushrooms...
The main thing about a freeform game is that it requires the buy-in of everyone involved and a good amount of trust between them. One person taking the game off the rails can result in things spiraling out of control.
