Yep. No, I don't do YTPs, about three or four years ago, I used to try to make Machinima vids. I got some great success until my YT account was banned. I came back months later, my acc is flourishing but I don't want to tell people the username as it would cause a lot of stuff with my friends lol.
Anyway, more to the point, I use SV for walkthroughs. No longer do I do machinima (did that stuff three years ago though). I never understood how to make a YTP lol. I only watched them!
