I finished this last night. I understand the raves for this one, since its production values are spectacular. The audio in particular is just fantastic. I was very surprised by how short the game was. I think Beyond Good and Evil took me significantly longer to finish. Still, it was a very fun, rated M, action/adventure title. A great game.
Having said that, it's a bit overrated. There are a lot of annoying parts in this game. Most people complain about Hades (and with good reason - it was dreadful). But, I hated a lot of the timed puzzles, and all the balance beam crap too. Climbing those 2 spiked towers in Hades nearly tried my patience to the breaking point. I remember how happy I was last night when I cleared the first tower. Then I saw there was a 2nd one and uttered a moan of despair.
One thing I was surprised about was how few boss battles there were. In the opening level you finish with the great hydra fight, and then you play through the bulk of the game before fighting the next boss! (The big minotaur which was also quite fun!) The ending boss fight(s) with Aires were pretty disappointing. Basically just a normal fight that took longer. Fighting the Kratos clones to protect your family was a nice twist.
Still the good - or great - far outweighs the negatives for me. I had a blast 95% of the way through. While the game is short, I was about ready for it to end, so I won't knock its length. I thought some of the combat waves maybe went on a bit too long, but that's a minor quibble since the combat was so well done and fun to play. Definitely a great game, around an 8.5/10 for me.
Now I am going to try God of War ripoff Spartan: Total Warrior. I expect to be underwhelmed!
