I think to appreciate the walking dead you need to not only have a taste for narrative, but you also need quite a degree of maturity. Im not talking about guts and gore and violence. Im talking about empathy, about understanding how hard it can be to make decisions sometimes, and accept the bad things that can happen even when your intentions are sound. For me, i was blown away by the attachment i formed with the little girl who is your ward for the game, i really worried about her and constantly caught myself checking on her first and doing what was best for her even when it was detrimental. It literally created bonds that have, to my knowlege, never been this well formed outside of the real world.
Its impressive, but if your idea of a zombie apocalypse is the idea that you and your mates would grab some weapons and have a great time, this might not be your thing.
