The game may be short, but it is far more memorable than many longer games. It's like playing a blockbuster movie.
Combat is loads of fun and the various style moves used in taking out hapless opponents never gets old, partly because the game itself is rather short. What you've heard about the game is true, it's only about 6 to 7 hours long. However, like the Call of Duty 4 campaign, each chapter is memorable, more so than almost any game I have ever played. This isn't because of an amazing story, but rather the vivid images and details that will come to mind whenever you think of your experience with this game.
Enemies are hardly varied, though, and you should be prepared to kill a lot of similar looking warriors with hats and ponytails. Regardless, killing them never ceases to be a delight, execution moves are like a God of War-style mini-cinematic, only more graceful. Nariko is the sort of hero that you can brutalize people with while also being unafraid to let your mom watch.
The production values are sky high and the boss fights are all truly memorable. Something that less extreme gamers may find annoying is the difficulty of the final boss fight. Without spoiling anything, once you think it's over, it's not and this final battle will easily add another hour to your play time. I really cannot imagine facing the final boss on hell mode, but you can try if you'd like to squeeze a little more replay value out of the game with this unlocked difficulty setting. The price to game ratio may seem large, but trust me, it's worth every last penny. Buy it new, buy it used or just rent it; this game deserves to be played.
