Playing Hitman they way it’s intended to play is fine; I’ve beaten both Paris and Sapienza with no non-target kills, everything was pretty much OK.
However, I also like to play Hitman in a serial killer mode: kill everyone in the level. Every single person. Try to not get spotted for as long as you can. It’s fun!
What’s not fun, though, is that the game starting to crash after certain point. Initially, I thought this was only in Sapienza, but after attempting the same thing in Paris lead to the same crash. It seems to be technically impossible to do this due to the crash. 1.05 didn’t solve the issue either.
