Been reading Syd's older articles, in particular Valdronius' article on Maniac Mansion.
Which reminded me of a little something that I found out a couple of hours ago: A 9 minute speed run of Maniac Mansion:
Not sure if it has been posted before, considering the video's from 2006, but it did get my attention.
There was also a 21 minute Speed Run on Day of the Tentacle, but it felt quite unnatural in cuts, specially comparing the progress with a full fledged walkthrough.
Regardless, 9 minutes seems awfully fast for a click and point adventure, but it begs the question if the game can be completed faster (official ending, not the Nuke ending or similar).
