Ugh, I hate when people speed run through their first playthrough of a game. That just shows how much they appreciate it. I like to be able to explore every bit of a game I really enjoy, and do and find everything the game has to offer. That way, I'm getting what I paid for, a complete experience. Especially if I really like the game, I want to be able to absorb every last piece of it. Until I've done all I can, then I play at whatever pace I want to.
I don't usually speed run, unless the game requires me to, but it does go by faster my third time around. Because by then, I would already know the game well enough to just blast through it. While still being able to get the complete experience.
