Along with Daniel's Dave Grossman interview, a new fan doc on the making of DOTT came out yesterday:
(This got a mixnmojo news post a week or so ago, but it wasn't publicly available at that point.)
As I said on Twitter, they mention that Hit The Road came out in the same year, which reminded me how little retrospective attention that game gets comparatively. I guess the DOTT remaster had something to do with that, plus it's generally thought of as the better game, but I love HTR too and would love to see a bunch more behind the scenes stuff for it.
