Now, the downloadable version has audio commentary, with one instance of a funny sound when I thought it would be appropriate. In fact, think of it as a shortened version of the beginning of Half-Life 2, just to fill you in on the story. The Youtube version is extremely truncated, low quality, and does not include commentary. There's two versions of today's video: Youtube and downloadable. As the title suggusts, I'm making my LP in Video form, with audio commentary from me on the way. So, I'm finally starting my Let's Play of Half-Life 2, released by Valve Software in 2004.
