After everything that happened (or didn't happen if you will) with the Back to the Future game, I really don't care much for Telltale as a company. That said, I think it certainly look like this game has potential.
I just wish Telltale would bring their games to Xbox, instead of just having mods and telltale fans trash microsoft on their forums. Why alienate someone like me - a casual gamer who several years ago picked up a 360 over a PS3, and don't have the money to get a PS3 now?
About the JP game - there is some gameplay footage you can get to from the telltale site. The graphics look good, and while it seems built around button-mashing quick time events, it does look full of danger and suspense.
