I gotta say I'm intrigued by the idea of having the Corps go across the sea total culture shock. Would the rest of the world even know that the Walls even existed? It would be really interesting to play out discovering the world beyond that knew nothing of them, mutual ignorance of each other so to speak.

The second idea sounds really interesting as well, I'm going to look the Neuromancer up but I would like to hear more about it. Self indulgence is fun, don't worry and I like to discuss ideas as well to work out something which works for us both.
