Forget all the gory, bloody, scary stuff surrounding this game. People treat it as if it were something edgy that had never been done before, when Mortal Kombat in the early '90s set the bar high.
This game has a different value. It has really good stealth mechanics. It's not ideal, but it gives you that Predator feeling of choosing the most efficient path, luring enemies etc. It has cool, challenging gunfights that are fun when you're on the highest difficulty — every bullet and headshot matters. The amazing soundtrack and sound design put you in the mood. Again, it's not the mood of a "Saw" movie, but rather the mood of a commando: an ultimate soldier who outsmarts his enemies and has the stamina, strength and aim to overcome them.
All of this together provides a good experience, something similar to what you get in "Hitman" games. It just has extra "gory" things, which is not a big deal. So yeah, it would be great to see it preserved here.
