Summary: Fist of the North Star: Ken's Rage isn't a groundbreaking game. It isn't even very good looking (sans the cutscenes which run at a very smooth 60fps), but it is a hell of a lot of fun to play. The game tells a portion of the story from the original manga series, and while there are some great looking cutscenes throughout, there's a lot of the story missing here.
Summary: Ok, this is a really weird thing, really: the first time I run this game on my x-box, I was surprised by the crappyness of the environment, and the technically very poor development of the game. Tons of enemies completely equal to each other, invisible walls, bare environment, quick time events when facing the final moves versus the bosses, poor story telling, unpleasant skill trees.
Summary: Great graphics and story. I didn't read the manga and I never watched the anime, but I liked the plot. The game has a musou style, and by that everything should be dynamic. The problem is it isn't. The characters fight in a slow way, making the gameplay dull. It was suposed to be faster, since they're melee fighters. But I think that's the main problem. It has a good set of characters to play and various modes.
