11 Years and 1000's of Hours of Gameplay Later I'm Still Learning How To Play Ninja Gaiden

Ninja Gaiden (Xbox) released in 2004, and since then I have played it (and its various incarnations) for thousands of hours. Literally. And even still I find myself, from time to time, learning new things. Either through experimentation or by watching videos/reading other people's forum posts. Just a couple of minutes ago I learned a new boss fight strategy while watching a Ninja Gaiden Black karma run video (Master Ninja difficulty) on YouTube. (For those who play the game(s), if you didn't know, you can OL UT Murai (if there's essence available) by first hitting him with >Y. Then simply OL UT him on the comedown.)

Now, don't get me wrong. I am not saying this depth is exclusive to Ninja Gaiden. Nor even video games.  Nor is this the only (or even close to the biggest) reason I love the series. It's just a small aspect of it that I find to be really cool and part of the reason I keep playing after all of these years. 

And for my long time readers, yes, I am still yammering on and on about Ninja Gaiden. It will never end so
