As of yet I've done several Let's Plays, some who I'm not proud of and some who I'm "okay" with. I started Let's Playing in 2010, doing it without commentary with Super Mario Galaxy 2, doing it as a guide post-release. Without commentary, I also did The Legend of Zelda: Ocarina of Time Master Quest who serves as one of my best works, cause of the sheer time put into it when recording and playing it.
Finally I got my hands on stuff that would allow me to do Live Commentary and I quickly did a sucky LP of Metroid Prime.
As of now I'm doing Pokémon Black and have just completed a 100% Walkthrough of The Legend of Zelda: Twilight Princess.
Other works range from Portal to Star Fox Adventures!
You've done a few games I think extremely highly of, The Wind Waker and Metroid Prime. I should really play Prime again myself, so until I do, I'll just watch your LP of it and reminisce how awesome that game is.
Hah, everyone has some terrible videos they are ashamed of.
Heck, with my own Final Fantasy X playthrough... it was so long (126 episodes) that by the end I was really proud of what I had accomplished, but being my first LP it was so bad at the beginning I'm always nervous recommending it to people.
