10 Video Games You Didn't Realise Are 10 Years Old

4. Ninja Gaiden

Few names in the gaming realm usher in a clench of the fists and the speaking of names through gritted teeth, but "Nnnja Gdnn" is easily one of them. Often cited as one of the most unforgiving and unrelentingly hard games in existence, it still had a brilliantly tight fighting system that saw you flying around the screen in a blur of sword-swipes and ninja stars, occasionally grabbing a demon for a spinning sky-high piledriver. Yes, a rebooted Ninja Gaiden had landed on current consoles, and it wasn't going to bow to your level whatsoever. With a first boss that went down instantly in the history books as having a checkpoint set far before him, only to then be incredibly tough even if you could get back to him without losing half your health. The whole thing separated the hardcore from the casual, and a whole host of potential fans were not just shown the door - they were booted straight through it while being laughed at from behind.
