This is from Torner's chapter, p 198:
The Big Model provides an example for theory as a team effort. The Forge participants formed a model that unified and connected different threads. Its components are hardly unique . . . But the Big Model arguably integrated the function components of an RPG . . . It was a first major synthesis that enabled key future work . . .
Good thing we've all agreed The Forge is terrible!
The same chapter, p 205, says
A core process of RPG play is task resolution: determining whether a player character succeeds at a task in the game world.
This is obviously contentious. And what immediately follows it is wrong: it discusses
fictional positioning, with reference to Baker's blog, but then goes on to say "Another model is DFK, devised by Tweet" but that is not another model: what has been described in the immediately preceding paragraph is an example of drama resolution. I think Ron Edwards has much more interesting things to say about DFK than Torner does.
Maybe this isn't Torner's best work - I wouldn't know. But I didn't find it terribly profound.
