I'm pretty sure cbob is still working on the game. Marty did side projects like 18Titans when he was unable to continue working on this during his breaks, but he never continued the game without cbob so I'm 90% sure cbob is working on it.
		
		
	 
truth is, only a patron could pass on info about cBob, and of what they passed on here, looks like cBob made several attempts to work, which, how to say, faded, with the months passing. it's more and more Marty doing the coding, this much i'm certain.. and the stories, by their telling style, look closer to Marty's side projects and have a bit less of what i daresay used to be cBob's "playfulness", so i 
assume the plot may have been laid out to a degree, which gives Marty the chance to keep going. others tell the same about the latter. it feels a little different.
sorry, to describe what exactly i mean turns out to be difficult. like from idk v0.9.7 or so, towards the end, book 4 "feels different". in some way.
