As many inventors throughout history who have been forgotten could tell you, it's not always about being first to market with an idea so much as it is about the product you package with that idea. Maniac Mansion kicked off the golden age of the Point and Click adventure game with the introduction of Lucasfilm Games' SCUMM engine.

While I love a good low budget horror movie which this was clearly inspired by, it veers too far into the Rocky Horror type of camp that isn't my cup of tea, so I've never been particularly fond of this game's narrative. That said, it's hard to ignore its significance and impact on hundreds of games that would come after; some of which have very much been my cups of tea.
