Crazy attention to detail.
Seriously! Thank you: I gave you a thumbs up. I wonder if there's anything else like that.
I completed my first play through on hard: it took me over 25 hours because I like trying to find all of the items, so I frequently clear an area and go back to dig out everything.
But right now I am so torn between replaying this on Survivor, trying the multiplayer (I was addicted to Uncharted multiplayer for years), or trading it and continuing on my PS3 backlog of games.
Normally, I wouldn't think twice about trying out TLoU multiplayer, but the Sony online pass (now that EA has dropped all of them) makes me hesitant. My Uncharted multiplayer friends say TLoU multiplayer is fun when you are on a full team. The game is really, really good in its intensity and brutality: it draws you in to the experience and you want to see the characters through to safety and you are driven to get to the end of the story. However, given the dark subject matter, dire situations, and the nature of the relationships of the characters, it is not as much fun as Uncharted.
Maybe I'll reconsider when the DLC comes out.
