1. Ninja Gaiden Sigma 2: 9.0 - This game has a lot of value: 4 playable characters, offline/online co-op, numerous weapons (each with a different style), chapter challenges, etc. And it has the best combat out of the four.
2. Dante's Inferno: 7.0 - This game is basically a GOW clone but less epic. Though I gave it some extra points for the story; it's hilarious if you read the Divine Comedy.
3. Castlevania: 6.0 - The writing is awful, and some of the ways the story is delivered (novel-reading) is terrible. The overdramatic voice-actor might sway you into thinking that the story is good, but it isn't. Gameplay is weak, imo. It's just a button smasher, and no camera control is annoying. Also, the game drags on and has a couple of filler levels.
Haven't played Darksiders.
