James Rolfe, the guy behind the Angry Videogame Nerd, finally beat Ninja Gaiden II:
I could not beat the first Ninja Gaiden for the love of God, but the second one, Mike and I defeated! We spent several hours passing the controller back and forth. Many shouts and curses! The last level in particular kicked our asses for a long time! But we did it!
All those early Ninja Gaiden games are lessons in torture and persistence and a good example of the ways that game design has changed in the past 30 years. Back then it was all about learning patterns. Now there are more puzzles to solve.
And while you still have to learn patterns today, there were some games where they were nearly impossible.
I don’t think I ever saw a Ninja Gaiden end screen until after I got a Game Genie.
