I'm very proud of my 2:19.62 Final Chase M1, but I did it back before I started recording. (I do have a picture of the stage completion tally that I snapped after finishing it, though... two pictures, in fact.) My 41.97 Sky Rail was a nice run too. Of the stuff I've got on video, I'm proud of my Cosmic Wall M5 world record (
http://www.youtube.com/watch?v=G4sYWVRskNs), because it's my first world record, but it's not a very fun or impressive watch if you already know about the route--more than half of it is just flying in a straight line.
I'm also proud of my SA2 Dark Side SS run(
http://www.youtube.com/watch?v=-77dBewKGVs)--I started from literally nothing, having made the decision to do the run right after playing the game for the first time and working up to it for almost two years--although I never got the chance to see if it would make it on SDA.
That reminds me, I need to get back to SA2 for a while and do something about my Final Chase M2 and 5 times. They're total crap. I should work on Cosmic Wall again too.
