The only thing Tell Tale Games have to accomplish, is to hit that twisted humor the old game had.
I'm not sure, really. I guess I'm not close to being a customer anyway. I scratch my head at people going down the street with ipods and telephones in their ears, which are really the consumers of the day. There were some funny scenes in the original, but I wouldn't have the same reaction to whack-a-rat I did then, or a lot of the puzzles. Should be interesting, anyway.
A pitfall for Tell Tale Games might be their episodic model. I still see a lot of opposition.
People are a little more used to paying recurring fees than they used to be. It wouldn't be a lot different than an online game if they added some kind of chat feature, but then I suppose someone would start shouting spoilers. Recurring fees make a huge amount of sense from a business point of view. I feel sorry for game companies. They live or die by the last release.
