A good read. I wonder what he (and others) would think of a point-and-click RPG like Syberia?
Definitely gated, but the story and character development is everything. Without the 'gates' you would just be reading an interactive novel (with not much in the interactive department...).
Still IMO a great game, though.
My own project, which I consider very "story-driven" uses 'gates' of various kinds at times, but they're meant to be a bit frustrating: You're trying to find somebody to save the world and everyone wants you to jump through these damn hoops. Doesn't anybody care? I'm finding it a tough balancing act with character frustration vs. player frustration.
