Super Mario 64 on the Nintendo 64 was durden77's most well known and longest Let's Play. It started on October 9, 2008, and ended on July 2, 2010, so almost 2 years. The reason for the length is because of constant slowdown issues, and durden eventaully reaching the desire to end these problems before he completes the let's play; in fact, the longest wait between videos was waiting for part 18, which took a year to be released. At this point and onward, there was no more slowdown.
