I still wonder if the cheese machine is a reference to some obscure story somewhere... I may never know!
I did come across this;
Cheez powered time machine But that's apparently something new, some graphic novel. Maybe Roberta was ahead of her time?
Many of those animals in KQ5 were Roberta Williams herself playing the roles!
. It was innovative at the time, as it was one of the earliest full-voice CD games on the market. Impressive at the time, but for some hasn't aged well. It also was the first sierra game to bring about the end of the parser. Thought many older fans of the series, criticized that change thinking it dumbed the game down, making things easier!
KQ6 brought rotoscoped animation (with live actors), an impressive for the time 3D introduction scene by Kronos, several well known and respected actors (so it was getting closer to the multimedia Hollywood ideal that Ken and Roberta wanted Sierra to move towards). Not sure if it ever got any criticism?
The thing about inovation, it also gave us things like KQ7 which brought feature length quality animation to computers aimed at a younger more family friendly audience (while her other game at the time, Phantasmagoria pushed movie quality live action, went more towards the mature audiences), and streamlined the interface (reducing it down to a single cursor + inventory), and MOE (which was Roberta's push to bring hardware 3-D graphics and action to PC and the adventure game genre). Both have been controversial to some of older fans, while also bringing new fans to the series.
