I remember Humongous, largely because I'm a big adventure game buff and the company was founded by Ron Gilbert, the creator of the legendary 'Monkey Island' series.
I played most of those, but not because I was within the target age group; I'm pretty sure I had them on, like, demo discs or something and must have played them on days when I was really bored. Sometimes kids' games have a certain appeal for adults, but there's really nothing worth of note with Humongous' games. They were solid titles for their demographic (I remember 'Pajama Sam' being particularly good), but nobody who cut their teeth on LucasArts or Sierra is going to pick up a 'Putt Putt' game and find an underrated gem
