Here is the history of the development of the game...
Pay particular attention to Davidson's involvement... They or rather there 'henchman' managers, tried to take the control from Roberta, and make the game on their own without her input ('ignore her')... This is likely the point where she threatened to pull her name from the game...
The Davidsons didn't like Roberta that much apparently and saw her as all that was unholy influencing children to ungodly ways (through violence and anti-religious imagery)...
After Davidsons left Sierra, she regained much of the control... She was able to pull the game back to her vision, and agreed to have her name on it.
However, realize, that many of the 'action'/'RPG'/3D stuff was purely Roberta's ideas, and she was discussing some of those ideas as early as 1995 (before Sierra was sold), long before she physically started making KQ8... If anything she had more ideas for bosses, that ended up being cut... It was actually 3D and combat that she first started on, in hopes she could flesh in the puzzles later on (which probably lead to some puzzles being cut unintentionally as well).
rereleased collections of the main Quest games.
Poorly conceived, buggy and incomplete collections... Like leaving out the original version of LSL1, the CD versions of LSL6, and no LSL7....
