Hm, I remember a few kids games... might not be so interesting if you don't like kid humor or playing around like a kid.
Stay Tooned (Sierra Online, 1993), a nice Saturday morning cartoon styled game. Funny as all heck, and some of the humor is immature yet quite sophisticated.
Recess in Greece (Morgan Interactive, 1994), following the monkey Morgan (as Odysseus) through the myths of Ancient Greece, especially as seen through the Iliad. Lots of amusing ADHD-inspired animations done by Vietnamese artists.
Not posting any others coming to mind, since I don't think they warrant "gem" status.
Oh, and if you've never played the Hugo trilogy, you don't deserve to call yourself a master a gaming.
