So, I intend to play again and try different things, but I'm just too curious: after the accident in the mines I told Shannon that my leg got caught up and was really bad. Later, Conway was limping. If you tell her you're fine, do you walk normally? That would be pretty awesome.
Did anyone experience any other significant changes?
Also, did anyone try turning off the lights while riding the mine cart? One of my favorite moments in the game!
