Not sure if anyone has mentioned this yet, but...
Telltale is accepting preorders for The Walking Dead, but also gives you a chance of snagging the Telltale "almost everything pack" with it for a total of $42.49. I think it contains most of the games from their catalogue. http://www.telltalegames.com/walkingdead/preorder-contest
I think the offer sounds quite good (I own none of the titles, but I have some interest in them), but I'm not sure if I'll have the time to play them.
If you compare the price to the Sam & Max Complete Pack on GamersGate
alone, I believe the offer on Telltale is much cheaper. Correct me if I'm wrong.
