Storytelling in the world of interactive fiction
Text adventures have been quietly experimenting with narrative gaming
for thirty years. Five authors from the amateur interactive fiction
community discuss the design ideas in their games — reordered
storylines, unreliable narrators, deeply responsive NPCs — and how they
apply to other kinds of games. (Rob Wheeler (mod.), Robb Sherwin, Aaron
Reed, Emily Short, Andrew Plotkin)
Get Lamp is going to be screened later that same Friday evening — 9:30 PM, it looks like..
