If you enjoy retro beat-em-ups this game is a must have. You're not gonna get the next God of War from this, but you are gonna get about 8-10 hours of some of the most stupidly fun entertainment you can get this generation. Got this from Goozex last month, I can definitely say it's worth $15.
I haven't played God of War 3 or Ghost of Sparta yet, but personally I liked this a lot more than GoW 1, 2, or Chains of Olympus (which was my favorite of the three GoWs I've played so far).
Thought the gameplay, graphics, insanity, and everything else were better, personally. Plus I'll take Logan slicing off some dude's hand any day over pasty white guy
Okay, so I did actually have a solid time with the GoW games...especially Chains, but still this game rocks.
