Adventure Gamers previewed The Walking Dead about a week or so ago (sorry). Written up by Emily Morganti, who's back scribing for Adventure Gamers after her stint at Telltale, the impressions include an overview of the controls and a taste of how the much-ballyhooed choice system functions.
There's also some obligatory talk about whether or not the puzzle volume and complexity will appeal to hardcore adventure gamers that gets extended in the comments, but I fell asleep so I can't tell you where that one landed.
