The ‘horrible size of the view cones’ is a thing that we in the real world call ‘peripheral vision’. The problem is that you’ve gotten too used to playing the game at the beginning, when the view cones were far too narrow, you could literally stand by the side of an NPC carrying an axe and they wouldn’t see you, totally unrealistic. It’s fine how it is now.
But with the door shutting and the karate chop pacifications, yes, those are broken, highly annoying, and need to be fixed. No disagreement there.
But the difference is, I get an odd satisfaction by working around those broken things and still getting an SA rating. For example, during a certain period of Elusive Targets last year, the choke hold pacification didn’t work. Half of the time it would result in a non-target kill. (Remember that period?)
During that time, you simply picked up more bricks, wrenches, lead pipes, etc, to make sure that your run had enough to KO everyone with a melee weapon instead of choke hold pacifications. And in a perverse way, there was some satisfaction to beating the game’s bugs. It forced outside-the-box creative thinking. Which is what Hitman is all about. How about rather than changing the view cones to fit your style, you change your style to fit the view cones. Use more distractions. Improvise.
However, there is no workaround for shitty, underfunded voice acting.
