I don't know if I'd qualify Dear Esther as a game. A ll your doing is navigating an environment. Its an amazingly pretty environment, at that, though. Its definitely worth the two hours or so it should take to 'play' it. Highly recommended.
I wasn't going to get Humble Bundle 8, but now I'm intrigued.
The new weekly deal is pay-what-you-want for Telltale Games: Back to the Future, Sam & Max Devil's Playhouse, Poker Night at the Inventory, Hector: Badge of Carnage!, Puzzle Agent 1 & 2, and Wallace & Gromit's Grand Adventure. Beat the average and get The Walking Dead.
