Man, I loved playing these games when I was younger. Love the Sierra Quest pack.
King's Quest being one of my fav's. I made it a goal to beat the series.
The first and second games were difficult enough, but because of the known fairy tale references, I was able to play through.
The 3rd installment of the game I found was the toughest one. Sadly, I have not beaten it, but that won't mean that one day I will try again. As said from other reviews, the puzzles are pretty difficult, yet satisfying if completed.
I suggest this challenging first 3 installments to any game lovers.
