Manhunt was and always will be lit
SPOILERS
Three words: Oh dear GOD!!!
You took something that already went up to 11 and took it up to 110. You're scaring me XD
This would definitely win cuz it indeed maxes out both pain and art, this is really genius!
However, a machine that can do this might not be very feasible so some corners will need to be cut cuz there's supposed to be some realism going on.
For example, the claw or tool that will tear into the victim's mouth (which is diabolical, those mouth wounds hurt like hell) could be removed. The victim will already spit a lot of blood due to their internal injuries (probably).
I would love to see your art one day! Do you have a BlueSky account or something?
