Like, the ending was maybe a minute and the ending credits were closer to 10 minutes? That's how it felt, anyway. I think we should have at least gotten an individual slide for each target based on whether they lived or died. I think there are about 4 titles you can get at the end, I got Emily the Just (non-lethal) and Emily the Clever (apparently I was ghostly enough).
There is a plus game feature that allows you to retain your runes and unlocks all the powers for purchase, which is cool. As with the first game, I immediately wanted to do a high chaos run, and then a few hours later... kinda didn't. Partly because 30+ hours is already a lot of quality time with roofs, and partly because I'm not super interested in fucking everything up, which is what the high chaos run ostensibly does. I like discovery a lot, so I enjoy finding new places I missed the first go around, but there are sections of the game that I don't enjoy retreading. I prefer interiors and don't like the open areas and rooftops as much.

( Now cheevy. Not really spoilery but whatever. )
Something I found interesting is 25% of players beat the game with Emily and 17% beat it with Corvo. I think the fact that the game starts from Emily's POV probably helps. 80% actually play it, and it's hard to tell by the cheevs but I'm gonna say 30% beat it at least once.
