As you may have noticed publishers have really been cracking down on Youtube creators such as Capcom, Microsoft, Activision blocking the recording of games in their latest portfolio. I don't really see how they gain to benefit from that seeing as it is free advertisement like everyone says. I think 9/10 a viewer who watches a playthrough goes out and buys a copy themselves. It just baffles me as it lessens the advertising on certain games through the gaming community itself.
