I finished Dishonored in a few days, that never happens! It was so much fun I couldn't stop playing. Oh noe! The video game threat!

I kept the body count as low as possible for the majority of the game and then cut loose in the last few missions. It took me a while to realize that you can get the "ghost" checkbox simply by remaining undetected, no matter the number of kills or dead/unconscious bodies that are found.

I didn't start using shadow kills (bodies turn to ash) until late in the game and it felt like a bit of a cheat really, but you can choose not to activate this power if you wish.

I had great fun doing drop kills on the tallboys from three or four stories. And add Half-Life to that list of games above too.
