SPOILER CITY
If you get desperate there's always Sierra's Original Hintbook collection!
Or, to put it in Sierra's words:
"If you're playing Sierra's 3-D Animated Adventure Games without a Hint Book, you might be missing half the fun!"
I have fond memories of the old red Sierra decoder, though it looks like GK didn't use it.

Yay!!!! Classic Sierra is Awesome!!!! Bring on more! GK2, GK3, Conquests of Camelot, Conquests of the Longbow, Quest for Glory (All - PLEASE, PLEASE, PLEASE), Colonel's Bequest, Dagger of Amon Ra, Phantasmagoria 1 -2, Lighthouse, King's Quest (All), Space Quest (All), Police Quest (All), Liesure Suit Larry (All), Torin's Passage, Willy Beamish....
It would be awesome to have the entire back catologue of Sierra classics formally organized in one library! GOG, my new favorite website... Make it so!!!!
Long live Sierra!

Not Sierra but a good old game...Freddy Pharkas, Frontier Pharmacist.

Yeah, as angryjedi mentioned, that IS a Sierra game and one of their finest. Gotta love that distinct Al Lowe style. You might like to check out his website which has some info on the game including behind the scenes stories and more!
