I think a a cool feature (that could be toggled off) would be a "Crit-Cam".
Every once in awhile your weapon or spell attack would randomly deal extra damage, and the camera view would snap into super ZOOM to show the death animation. It might be an Instant Replay feature, where you get to watch but the game world doesnt get to affect (kill you) in the mean time, then play returns to normal.
When you kill a mini-boss in a 3D game, there could be a Boss-Cam where your last couple seconds of heroic fighting are replayed in Zoom from a different angle.
