If you want to read more dirt on Telltale’s abrupt closure, look no further than this article from The Verge. There isn’t a whole lot of new information in there, but it serves as a good summation of the time leading up to the closure.
Worth noting is the confirmation of what a lot of us suspected: The Walking Dead-fatigue is indeed a thing, and good as season four could have been -- or will be, as TTG, the classy joint it is, is shopping around for another company to finish up the remaining episodes -- the games just weren’t selling. Couple that with two investors that weren’t as ready to put money up as the company thought they were, and here we are.
Don’t take my word for it, though -- go read.
