If you can leave that excellent demo alone for a few minutes, you could always pop on over to Locker Gnome to read their new interview with Telltale Games CEO Dan Connors.
Dan: It?s obvious that story telling in games is on everyone?s mind in the development world. Coming out of GDC its all anybody is talking about. To me this is good news for adventure game fans, because it means companies are going to focus their technologies on better storytelling. As a result, I think there will be elements from adventure games introduced into more games and greatly enhanced. At the same time some elements from adventure games will go the way of first person jumping puzzles... I think every adventure game person will readily admit, that using every item with every thing to get past a puzzle, and move through the story, is seldom fun. So in trying to solve that, and make the genre more accessible, I think you will see interfaces and puzzles continue to be more straightforward and less complex.Those who have been following Telltale since they formed from the defunct Sam & Max team will know most of this stuff already, but it's still worth a look.
