My friend gave me the original Xbox version of Ninja Gaiden after I bought my 360. I played it up until I reached the first shogun on a horse, which is only about 30 minutes into the game, because it was so fucking hard. Then I tried it again a couple months later and beat him finally, only to have to face two shoguns on horses. So now it sits in a stack of games where it will stay until I muster up the resolve to try again or give it back to my friend.
