I'm thinking of starting my fantasy campaign with the players having no stats. A mystery start, with the PCs emerging as blank slates emerging from a magical event (or coccoons, or something) with a body form but no immediate knowledge, past history or items. They would choose a body form (race) and then we start playing to see what happens, exploring the somewhat surreal fantasy world with its strange contradictions and bizarre inhabitants.
They pick up skills as the PCs travel through the world (and the player expresses an interest in being capable in something) as memories returning to them. Likewise for attributes. For example, a player that starts thinking about how the plants and animals work might get a point in Druidism or Farming or Outdoors. There is a system behind all this but it would not be visible to the players until much later.
This would be a pretty freeform game focused on exploration, in imitation of some of the weird comics I used to read (Moebius's Airtight Garage, Donjon, Heavy Metal movie, etc.), where the abilities of the protagonist(s) are never clear and fluctuate quite a bit.
What do you think, is this just asking for a clusterfuck of dashed expectations or would it be fun?
