I remember Maniac Mansion, I played it as a kid. It was a) extremely scary and b) impossibly hard. Although I imagine that was because of my age mostly!
It came in a bundle with Monkey Island, Loom and Zak McKraken.
Zak McKraken and Maniac Mansion were the two I couldn't make any progress on!
For me the most impressive thing about Maniac Mansion is how more advanced in terms of gameplay it is, compared to many graphic adventures that came later, since you can select different characters and still beat the game, by solving different puzzles.
Later adventures had better graphics/story/characters, but were more linear than MM.
Thanks to the parent for the kickstarter heads up: I will be backing as soon as I get home!
Maniac Mansion gave me nightmares about nuclear meltdowns when I was about eight. It's still a bit creepy as an adult, but the humor elements are a lot more obvious.
