Really close to a ten. Love playing this, love the style, love basically all the important things. However, the execution of some story beats can be a bit clunky at times, particularly relating to your choice to spare or slaughter. There don't seem to be any major consequences on the events that unfold if you settle on the latter, and it more just kinda serves to make you feel like a dick. It'd probably not matter much if there wasn't really a pacifist option to begin with. Hard to say.
