@NoelVeiga: The only game I've seen recently give that much effort was Ghostbusters. Say what you want about the game itself, but someone went to the effort of totally nailing Bill Murray's casual slouch-walk when Venkman's wandering around. It's all in the details.
@NoelVeiga: You're dead-on about Marty. The voice is great, but he doesn't move right. Michael J. Fox was almost manic as Marty. This version seems much slower in his actions. But hey, we only saw a glimpse, right? Maybe when the full episode is out, we'll see more of what we'd expect from the character.
@Azu-nyan: I wonder if it has to do with Telltale's Strongbad Wii game. Maybe it didn't do as well as they hoped or something, so they don't see it as a viable platform... I could be entirely wrong though.
Oh awesome! Can I please sit through another origin story I already know and have known for years and years? That's great. Maybe bookend this with re-learning how Peter Parker became Spiderman and it would be a perfect summer...
