Really? Moldvay Basic? How would it be done?If you can make 4E a narrative game you can make any edition of D&D a narrative game.
I've actually played vanilla narrativist AD&D. I've posted in this thread about why AD&D is not the best vehicle, and about some of the challenges, particularly in respect of action resolution.
This is why I come back to issues around familiarity and experience. Assertion and unreasoned conjecture are cheap. But these are empirical claims: so what's the evidence?
