These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: LionelStarkweather from the first game is a rich man who creates Snuff Films for his own pleasure and profit. Using his fortune to acquire convicted death-row inmate James Earl Cash, Starkweather sets him loose in an urban jungle while hunted by gang members and corrupt law enforcement. Starkweather constantly ups the stakes by putting others in danger and even has Cash's innocent family kidnapped to face almost certain death ( they all end up dying). Starkweather's prize fighter is an insane, naked man wearing a pig's head named Piggsy who has clearly lost his mind through what Starkweather has put him through. Starkweather's voice dogs the player throughout as the depraved millionaire positively revels in the horror and brutality he creates.
Disappointing Last Level: The last few levels of the first game mostly abandon the stealth elements and executions in favor of gunplay. A large chunk of the second game falls prey to this as well.
Fridge Brilliance: A game in which a sick guy sitting in front of a computer screen in a darkened room encourages the player character to violently kill people for his own pleasure - an incredibly brilliant postmodern satire on violent video games?
Hell Is That Noise: For both the player and the antagonists. The sounds of roving groups of hunters taunting you in the distance can get incredibly nerve-wracking, but it's imaginably far worse for them to see their buddy investigate that weird noise from inside that abandoned building over there and simply never come back out. Also the OST, which was released on CD, is both creepy and well-composed horror synth in the vein of slasher soundtracks from the 80's.
Overshadowed By Controversy: Both games had gathered mixed reviews, damning the gore but praising the atmosphere. Yet politicians bring this up as an example of a "murder simulator", and one murder incident led to a public outcry in Britain, which normally never censors a game, and shops there were hesitant to sell the game until it was proven the game wasn't to blame and the perpetrator never played itnote the victim in fact owns a copy.
Paranoia Fuel: If you wore a headset while you played, noise that you made into the headset caused noise in the game. This literally allowed you to call over badguys to kill them, but the inverse was also true: if you were hiding in the game, the player had to physically be quiet.
Rated M for Money: "Blood and Gore, Intense Violence, Strong Language, Strong Sexual Content, Use of Drugs." These are the content descriptors for the second game. The first game only had the first three.
