Saying that Ninja Gaiden is not enjoyable would be a lie. As far as action-platformers go, it presents one of the most original set of gameplay mechanics of the era thanks to how it matches Ryu’s wall-climbing ninja abilities with basic but satisfying combat. Additionally, the way it balances good storytelling with action is a very rare sight for the genre, especially when the library of the NES is considered. Yet, it has to mentioned that the amount of satisfaction one will be able to get out of the game is strongly related to their tolerance for irregular enemy-spawning, which often threatens to undermine the great work that was done in terms of level design and vaporize it into sheer frustration. If players are able to look at that problem as a rough edge of the era, they are sure in for a treat. If that is not the case, Ninja Gaiden is still worth a look for its originality, but the journey may not last long on account of perceived unfairness.
