I was shown this by someone else. It's a fairly revealing interview, in all, and gives us some insight in his current feelings toward KMVR.
A mix of blue screen and VR? Interesting compromise.
The interview is well worth a read. Raven doesn't seem to go down that well with him, either!
Well, from a personal standpoint, while I enjoy Raven, it doesn't appeal to the same aspect of me that Knightmare appeals to.
Knightmare was essentially a strange mix of [western] cRPG and roleplay. Raven... Is Mario Party Medieval Edition: The Gameshow.
(Of course, since I read the interview months ago I could be completely misremembering the content, but Tim Child's point about the Crystal Maze and artificial build-up to a climax is an interesting one, although I don't agree that the more open ended nature of Knightmare is 'better', simply less traditionally gamey.
