I probably don't need to say this since everyone else has already, but very nice job with the trailer, Telltale!
The graphics are simply breathtaking. The animation, the landscapes, the characters - it's all amazing. Like nothing I've ever seen in realtime 3D. The characters look very good now that I see them in-game (On a side note, does anyone else get reminded of Sam the dog when Smiley smiles near the beginning of the trailer?) My only VERY minor complaint is that some of the characters have some noticably rough polygon edges (like on the rat creatures and Granma Ben), but I'm sure this is being worked out.
The voice acting is really good all around. I wasn't expecting Fone to be so low, but on the other hand, a high and squeaky Mickey Mouse voice probably would've been annoying. I'll probably grow to like Fone's voice over time (like I did with Max in Hit the Road when I was expecting a higher voice but ended up loving the voice he has).
Anyway, again - extremely nice job! I'm eagerly anticipating the release this September.
