My username is the name of the main character in Kingdom Of Paradise or Key Of Heaven, the title of the game depended on the localization. When I bought the game in NA it was sold as Kingdom Of Paradise. I picked this name because I thought that KOP/KOH was a hidden gem in the PSP Era, and I liked the protagonist so I picked his name for my username. Also for a trivia, you can say my nickname if you let the four letters in my username be silent.
