Telltale is a busy place to be at the moment: not only is it working on the recently unveiled Puzzle Agent, it recently acquired the rights to produce episodic Jurassic Park games, not yet confirmed for WiiWare but a good probability considering the company's past.
Now we've learnt that the studio is also producing episodic games on another Spielberg-related franchise, bringing Back to the Future back into the present with the first title expected to launch on WiiWare, among other platforms, this Winter.
Little is known about the titles so far, but Telltale's CEO Dan Connors had this to say:
The games are going to exist within these worlds. I wouldn’t call these games sequels per se but a new interpretation of their worlds for a new medium. For one generation, it’s an introduction to these series. For another generation, it’s a thing they can look back on and something they can share warmly with their family and friends.
Sounds like you'll probably have to use your hands... like a baby's toy. Expect plenty more Back to the Future dialogue quotes as the game takes shape.
