Doing a second playthrough of Dishonored, this time a high chaos (or in simpler terms, kill anything that moves) run. I have to say, it's so much more fun when you can actually play with all of your toys. When you go non-lethal stealth, all of those grenades, spring traps, incendiary crossbow bolts and plain old bullets just sit there collecting dust. Don't get me wrong, there's something to be said for sneaking around, quietly knocking out guards with tranqs or a quick chokehold, but it's nice to be able to just kill them in a variety of rather creative ways.
Come to think of it, that seems to be a running theme with stealth games. They'll give you many different ways of killing your foes (many of which are an absolute barrel of fun to use), then tell you can't ever use them if you want the best ending or score.
