I've played hitman a whooole lot over the last year or two, but it's been almost exclusively the roguelike mode. It was only very recently that I decided to properly go through the singleplayer campaign - and not just go through it, but do every mission story on every level.
Having just finished Hitman 1, I feel like I've started to see some interesting design throughlines and thought it'd be fun to talk about and pick apart the mechanical decisions involved. Just be warned; this is going to be very, very long.
