It's kind of funny. With video games, I talk to the game. Usually it's something like, "Holy crap. What the Hell!? ARE YOU FRIGGIN KIDDING ME!?"
But when I'm working I talk to myself all the time. It helps me stay focused. That's not wierd... Right?
Edit: Actually, I have to admit I talked to myself a LOT when I played the Stalker games'
"Alright, so do I have enough ammo? Ok, cool. Let's go do this."
"Oooh, what is this, a cave-thing? This looks interesting..."
"Okay, I'ma goin in.... Shitshitshit, it looks scary, not going in... Okay, NOW I'm going in... See, it's this kind of hesitation that makes you suck at dodgeball..."
"So I'm in the cave... Dead guys, that's not scary at all. See a bunch of those... SHITSHITSHITSHIT WHAT IS THAT!? WHAT THE HEL... And I died...."
Just one of my very many conversations in the game. I routinely had to psyche myself up when exploring in these games.
