In contrast to the last game of Solipsist (http://www.solipsist-rpg.com) I ran I've been trying out the game as a one on one over e-mail, and it seems to be working well. It's a different experience from doing it with multiple people, mostly because the single player's Vision is so much more dominant in shaping the world and the direction of the story than when you are juggling the Visions of a number of players. I've been especially struck by how much character creation in Solipsist appears to also be world creation.
Anyway the actual play thread is on Collective Endeavour, where I plan to add more as further sessions are completed (a session in this context being many days worth of emails), but feel free to comment here.
