I agree to a point. I didn't buy God of War 3 for $110 when it came out because reviews say it was "short." I wasn't hugely convinced to invest a large amount of money on a game I played a demo of that I thought was good (I had never played God of War prior). I waited months for it to come down, I eventually bought it about 3 months ago for $50, which I thought was a good price, and the game was definately worth it.
Back to Enslaved, I just picked it up this afternoon used for $34.Will give it a play tomorrow once I get some business out of the way, looking foward to it!
