Walking Dead is based more around the relationships between characters in a survival situation that get along like six velociraptors in a tent with only one sleeping bag. It makes the claim that all your decisions will have an impact and when a game says that, it usually just means that one bloke will say a different line or have a screwdriver jutting out of his temple two scenes from now, but by keeping the episodes short and the enviroments tight, Walking Dead can make your decisions seem to have greater impact than a piss in the wind.
