I recently bought and finished Shadow of the Colossus.
It was an incredibly engrossing experience and easily the best game that I have played in a long time. The art direction is top notch and the gameplay is fluid and innovative.
The entire game is focussed on seemingly impossible battles with a series of giant creatures of ambiguous composition (they look ancient, spiritual, animal, and artificial all at the same time).
The battles are confrontingly visceral and really communicate the mindset of the main character. Because of this, I actually found the game a little hard to play at first. However, I perservered and it was very rewarding.
My only real criticism of the game is the difficulty and pacing. Most of the colossi were incredibly easy, but the final few were quite difficult. I spent around 3.5 hours on the first dozen or so, 2 hours on the second last one, and then 2.5 hours on the last one. That’s not very balanced!
A possible spoiler (but not really) after the jump.
Conclusion: Highly, highly recommended
I don’t think that I am giving anything away for saying this, but it looks like it could actually be a prequel to ICO. (Anyone who has finished the game should see why.) If so, I like that they didn’t market it as such. It’s very different in style and may have been misinterpreted if thought of as just an ICO prequel.
