I went into the game completely blind and didn't realize there was a multi-player component. During the final level, my traveling companion was spotted by one of the snake monsters and was subsequently attacked.... and I flipped out. Not out of anger or frustration, but because I was genuinely afraid for his (or her) safety. It was a fantastic moment that made me realize just how attached I had grown to this person who was a complete and total stranger less than 2 hours ago. I didn't know anything about them, what they're favorite color is, what bands do they listen to, what their hobbies are, nor even a simple name to call them by, but I did know this.... we were in this together and neither of us was getting left behind.
