Apparently, Digra05 was the stage for (another) discussion on ludology and narratology. Some places to read about it:
Grand Text Auto (DiGRA05 in Pictures).
The Ludologist (N&L: I Can’t Take it Anymore!)
Greg Costikyan's blog ("No Justice, No Peace": No Truce in the Narratology/Ludology War).
Janet Murray's keynote (The Future of Electronic Games).
It will be hard to find the time to read all this...
