Hey I watch your walkthroughs. Theyre very well done... Too well done. You play the game first then play the walkthrough dont you? Either that or you have near god perfection.
Tip: Usually I'll play a portion of the game then play through it again and record it. That way I don't have to think too much and if I mess up I don't have to restart my walkthrough from begining. It really helps me perfect a walkthrough.
