I don't watch video game videos much unless it's a new game (for example the Baby Pac-Man 7800 in development) or a rare game that I've never played before. I don't need to watch someone review Flag Capture for the 2600. I would rather read Video Game Critic's concise and humorous reviews. Unboxing videos are just dumb IMHO.
YouTube is awesome in that you can find content on whatever suits your fancy. In my case I enjoy watching concerts whether they're new or old. Also you can find movies and old TV shows that aren't otherwise available on DVD.
