I have personally played many games just like any gamer from old school consoles to our glorious somewhat advanced PS4 and xbox one consoles also back in my dark days of no sleep playing MMORPG's online... >> don't ask about that dark time! 0_o but imo i have never played a game harder than Ninja Gaiden that game was srsly amazing the feel of finally feeling like a badass beating an insane part, killing a boss and the most rare moment that hardly anyone even got too even if they had the game was actually beating it! People say Dark Souls was hard I do not disagree with them but Dark Souls is a slow paced game as far as char movement, weapon dps and the reaction time to dodge and block was on an easier lvl compared to the insane fast pace of Ninja Gaiden srs fast reflexes r needed to beat that game.
