1 DARK SOULS 3 (PC, PS4 XBOX ONE)
Dark Souls III is an action role-playing video game developed by FromSoftware and published by Bandai Namco Entertainment for PlayStation 4, Xbox One, and Microsoft Windows. It's the hardest game ever.
2 Spelunky (PC, Mac, PS3, PS4, PS Vita, Xbox 360)
Spelunky is an open source indie platform video game created by Derek Yu and released as freeware for Microsoft Windows. It was remade for the Xbox 360 in 2012, with ports to the PlayStation 3, PlayStation Vita and then back to Microsoft Windows. This game is insanely difficult.
3 Flappy Bird
Flappy Bird is a mobile game developed by Vietnamese video game artist and programmer Dong Nguyen, under his game development company dotGEARS. The game is widely loathed, punishingly difficult.
4 FASTER THAN LIGHT (PC, MAC, IOS)
Faster Than Light is a top-down roguelike space ship simulator created by indie developer Subset Games, which was first released for Microsoft Windows, OS X and Linux in September 2012. The hardest part of the game was the fact that you had a time limit to complete all of the tasks.
5 Alien: Isolation (PC, Mac, PS3, PS4, Xbox 360, Xbox One)
Alien: Isolation is a survival horror video game developed by Creative Assembly and based on the Alien science fiction horror film series. This game is my favorite horror game ever.
