Adventure games didn't go anywhere. They're still popular with fans of the genre (Telltale, David Cage, etc.), and adventure elements are now part of other genres like Action-Adventure, RPGs, etc.
Hmm yes but telltale almost went out of business. And since their revival their games have been more actioney. I don't think their games were truly inventive either. Their monkey island episodes were ok but nothing as characteristic as the real ones.
