Oh, I think that modern games like the BioShock, Mass Effect, Assassin's Creed, and Portal series (all of which started at almost the same time!) certainly tell interesting, involved stories that are the match of most adventure games. Not to mention RPGs with many thousands of lines of dialog. The pacing of adventure games is perhaps still friendlier to those who want to savour the story and think about things without being pushed along by action scenes.
