    I Wanna Go Fast

    Most SCI games keep track of CPU speed. They do this at startup in a room commonly known as speedTest, and save the recorded speed in a global variable commonly known as machineSpeed. Initially, there was no upper limit. This leads to bugs in Leisure Suit Larry 3. In the exercise room, the...

    We all know how, in the original Leisure Suit Larry, the title character would commit suicide if he didn't lose his virginity by sunrise. I even uploaded a video of this on YouTube.
