More Portal from GDC
Portal lead developer Kim Swift and writer Erik Wolpaw said some insightful things at their postmortem at GDC;
Wolpaw introduced the “crackpot theory” which led to this integration: The feeling that games tell two stories: the “story-story” and the “gameplay-story.”
“If you lower the delta (the closer you bring them together),” he said, “it makes the game more satisfying.”
When you think about it – especially having played portal – it’s really obvious, but coming up with it is really the hard thing.
