I'm a little old school. You said emotions in games and I thought of Infocom's games. Floyd in Planetfall is the classic example, but in Sherlock: The Riddle of the Crown Jewels I remember feeling oddly embarrassed when Sherlock Holmes tut-tuted at my use of the in-game hint system, and then relieved when I was with Wiggins and the urchin encouraged the use of hints - we were two scared people out of our depth and looking for any light in the darkness, even if Holmes would disapprove. I was similarly proud and happy when I saved the girl in Covent Gardens, not because I'd solved a puzzle but because I was a doctor and I saved a child's life.
Doctor Who as a superhero.... Interesting trivia: There's at least one version of the Doctor who shares a universe with, of all things, the Transformers and the Marvel heroes like the Avengers and the Fantastic Four. No lie: Marvel UK held the license and while I don't believe there was any direct crossovers*, their efforts to pimp their new character, Death's Head [http://en.wikipedia.org/wiki/Death's_Head], saw him guest-star in Doctor Who comics, Transformers comics, and main-line Marvel comics, with the changes he suffered at the Doctor's hand carrying forward to later appearances.
(* There might have been, though, before Marvel UK's "implosion" when the smell of desperation was in the air.)
(And who said the Completely Useless Encyclopedia was useless?)
