6. Red Dead Redemption's Manimals
Was this just another one of Rockstar's ways of messing with us or could it be some of the creepiest open-ended world glitches ever seen? Spend enough time out in the lawless west of Red Dead Redemption and you will eventually begin seeing the manimals. Usually your first encounter with one will be a man flying high above you in the big blue sky. Sure logic may tell you that it's just the game replacing a bird for a human, but seeing that human way up in the sky flapping his arms is just a bit creepy. And if you find bird people unsettling then don't stick around for the horse people. Simply people with horse faces that you can jump on the backs of and ride around the western plains as if they were real horses. Not to mention dogs that will not only talk to you, but also draw a gun to shoot you down if you look at them funny. Don't even get me started on snake people.
