Ok, I am going to state this categorically. This game should be in the top 20 Master System games. The only reason it is not as far as I am concerned is because it is pretty uncommon and as such was never likely to be voted in any top 20 lists. I honestly cannot fault it in any way. The presentation including when you lose, and also when you complete the game is amongst the best for the system of ANY game. So to answer the original question, is it worth the time and effort finding Ren & Stimpy - Quest for the Shaven Yak? A resounding yes, take a week off of work and book a flight to Brazil if need be! You'll thank me for it! :-)
