Four hours to beat Maniac Mansion is ridiculous. When the game was released back in 1987 it a 40 hour game.

Over 800 gamers tried and utterly failed to beat a classic 80s game without a guide

The Adventure Game Aptitude Test is the first of its kind, and the initial results are incredible. Only two people beat a three hour game without help

@grumpygamer I spent WEEKS solving it on the C64.

I had a friend at school who claimed it was possible to run past Edna in her room, getting up the ladder, without getting caught on his pc-version..
I played it on the C64, and it sure as "#ยค"# wasn't possible there. Probably spent a few days trying that before finally getting her out of the room :)

Good times (and no internet, so "ask a friend" was very much what we had to do.)
