 In a retrospective of the Ninja Gaiden series , Eurogamer said that Ninja Gaiden III was the only game in the NES trilogy not to make it to Europe . They made similar criticisms about the difficulty level , saying that the North American version was made more difficult than the Japanese version by utilizing limited continues , making the enemies much more powerful , and removing the password system present in the Japanese version . They said the story was too outlandish , calling the plot , of which a short @-@ lived anime Ninja Gaiden series would loosely be based , " a glorious load of old bollocks " . While the version from Ninja Gaiden Trilogy for the Super NES remedied most of their criticisms , they said that the game added new frustrations which included slower framerates , lower @-@ quality controls , and the omission and shuffling around of several tracks , which they said " is precisely the sort of thing that makes die @-@ hard videogame fans apoplectic with rage " .
