What is the most difficult game in the world ??

Devil May Cry 3...I really suck at button mashing games, so the majority of it had me rage quitting xDD

For me all Devil May Cry 1 to 3 on Dante Must Die and Hell and Hell modes

Dark Souls is the most difficult game for beginners and new characters.

The Impossible Game :D,,,

I Wanna Be The Guy

I Wanna Be The Guy: Gaiden

I Wanna Be The Boshy

and all other games with "I wanna Be"

Go and try them, Dark Souls felt way too easy after playing these games.
