I grant you, Telltale did make a good number of adventure games in the classic style, e.g. Sam & Max, and then also applied them to licenses like Wallace & Gromit and Back to the Future... but I feel The Walking Dead was a different type of game. More a narrative and character led game, like a visual novel, rather than a puzzle game of any kind... and as that was so successful, they stopped making the point'n'click puzzle-type adventure games.

Would you consider them to be the same genre, an evolution, or a different genre (that perhaps Telltale spawned?)
