17. The Walking Dead: Season 1
Switching gears entirely into a far more narratively-heavy experience, Telltale's take on The Walking Dead has become one for the ages. Supremely moving and engaging in a way that the show can't seem to come close to any more, you play as Lee Everett looking after small girl Clementine, your intertwining adventures providing the perfect setup for all sorts of horrifically grey moral choices along the way. In the end, that's exactly what made people fall in love with the franchise in the first place; that idea of the zombies being secondary - an external catalyst to the true horror that's right under your nose. Just how far can we push human interaction in various directions, before the results are more disgusting and unbelievable than the context itself? Season 2 of this would drop the ball somewhat after a stellar first batch of episodes, as it's this first innings people refer to whenever they're praising the series. Telltale established themselves as some of the best storytellers in the medium, before pulling off the seemingly impossible; Walking Dead's narrative gives you the impression that everything you're doing and choosing is of your own volition, but the entire time it's the developers who are really behind the strings - something that'll blow your mind in all the right ways once you analyse how your actions compare and contrast with others.
