About as much as it is possible for a naked soul to suffer; or alteratively, depending how early I got my claws in, not at all, seeing as he would be completely replaced by a Sasuke akin to the one in Nugar's People Lie ficverse (who I actually like)...
Humanity as a whole has not become any less stupid in the last ten thousand years, even if it has become better educated...
Totally not pony related, but I just wanted to gawp, as Obsidian's kickstarter for Project Eternity (i.e. a new BG/Torment-style isometric party RPG) just concluded, a hair short of $4 million dollars ($3.986 million). Particularly impressive since the last million dollars or so came in the last four days, half of that in the last day! I have - for once - very high hopes for Eternity.
