There are very very few things digitally that I have problems with. As a gamer, I know the difference between reality and make-believe, and as an adult, I know that games are-mostly-a moral grey area, neither black or white. But there are few games I would classify as bad. A few, I would classify as so morally objectionable that I will refuse to play them.
Now, some would wonder why Postal 2 isn't on this list. The fact is, it's a pretty blatant videogame parody- a game that is supposed to make fun of american culture and game culture. The character you play as does say he doesn't like videogames, and let's face it, while the easy modes are pretty objectionable, the 30+ difficulties serve only to prove that this game is outright bonkers and cannot honestly claim to be a "going postal" sim... unlike the first game.
So here's the games that I would classify as immoral:
1. Manhunt 1 and 2
As fun as these may be, they are outright, blatant murder sims. They cannot share the same "goofing off and causing havoc" like gta or "action-movie sim" like Max Payne. Manhunt is one of the few games I would never mention to anyone outside of the very few hardcore pc gamers.
2. 6 Days in Fallujah
a game that was thankfully never released. It was a faithful recreation of Falujah. It was a third person shooter, so you weren't immersed, but still, the World War II games and Vietnam games can be more realistic because those wars have passed a while ago. This game is something I really find objectionable. I would simply refuse to press the fire button.
4. Ethnic Cleansing/Muslim Massacre
This one's a no-brainer. A cheap way to earn some money by terrible men, made in FPS creator. Terrible and honestly bad. Both of them.
5. School Shooter North American Tour
This one was a half life 2 mod that was banned by gamers first. Not even worth looking up, it takes the issue so lightheartedly as to have telephone noises on some of the guns.
6. Metal Gear Solid 5
Now, this game has artistic intention, with the sole effort of advancing games as an artistic medium. It doesn't make it okay, I'm not a fan of the franchise but some of the content is outright blasphemous, and the entire game is 1 hour long, and 60 dollars to boot.
7. Every Chinese Propiganda Game
Yeah. Not cool man
8. The Suffering
This one... is just disgusting. it's a gamer's game, unlike the rest on this list, but it came out for the sole purpose of riding on the backs of the rest of the 2000's era controversies when the xbox classic and ps2 were almost dead. Feels like it's beating a dead horse to get some cheap kicks.
9. I Have No Mouth and I Must Scream
This game is actually a very artful masterpiece... just don't play it unless you are sure you are okay with its psychological content. Really.
10. Grezzo Due
A Doom-engine game featuring entirely of stolen content and hideous anti-catholic genocide. The game is entirely in Italian, which makes some sense... but I'd never touch it again. I tried it to see for myself if it was bad and it was.
11. Call of Juarez: The Cartel
The only time you will ever hear cursing in a Extra Credits educational video. This game disgusts me. It racially-distorts facts about the cartel wars in mexico to scare american gamers against mexico. It's truly horrible.
11. "christian" action games Like Left Behind: Eternal Forces and Catechumen
These games sicken me. As you may not be aware, I am a Lutheran, one of the most open-minded churches out there (we even allow gay pastors) but even then I find these games to be one of the most sickening things. Games that explore the christian faith should be open to the darker parts of faith, and teach people about the coping with existence, doubts, and other things, but games that feature beating atheists until they convert, or slaughtering gay people and satanic cultists, to me, are sickening.
And that's the list. While manhunt may be played by yours truly at some point just to test it... I probably will never touch any of these games. This list was to prove that I actually do find some games objectionable, and to hopefully educate people on where the boundaries lie in games.
