I used the be a lot more OCD when I was younger, a little on the stubborn side but it's what got me mastering games. Now I just try and do as much as I can. I'll always play alongside some solid online resources that aid me in not missing important items etc. In truth I don't play many new games, I'm on more of a nostalgia trip.... I master Final Fantasy VII once a year though, that seems to be a compulsion.
