This should be really interesting. You could make the argument that it's a study of what happens when you let a decorated set of game developers do whatever they want to do rather than appeasing the suits. Will the game blow away the design-by-focus-group competition?
The other interesting question is -- after all these years, do these guys still have that spark of imagination and inspiration? I mean, we're talking about some of my favorite games of all time, here, but it's been such a long time since these guys made them.
