This is one that I was big on wanting to play but didn't have a computer at the time so I looked at grabbing the PlayStation version. I never got it, or the Saturn version, or the sequel on PSOne because my local stores either only carried one copy (sold out immediately) or none at all (they had no faith in point and click adventures).
I became a huge fan of the genre after playing Maniac Mansion on the NES many years prior. Sadly, console gamers were often left out of the fun with this genre.
