I absolutely hate it when people make tutorials and they either don't know what they are doing or it's very low quality. Somebody tried to do a walkthrough for a game they haven't even played before, and quit not even halfway in it, but still posted it on YouTube.
I'm watching these horrible tutorials about The Sims 2 right now. The Sims 2 lets you record right on the game, but these "experts" use a video camera! If you're worried about the video capture in-game being low quality, then why not download a Hypercam? I got mine free! Or maybe get a tripod for the camera, OR just lay the camera on a flat surface!? Huh!? I can't tell what you are doing because you can't type in the cheat code and hold a camera still! See what you made me do, you made me go First-person to Second-person! (I still don't know the difference between those.)
Anyways, I get the feeling that these people know that it's horrible, they put it up, but disables all comments.
