Shadow of the Colossus is reason alone to get this collection. With ICO in the mix, there is no way you can go wrong.
With Shadow of the Colossus being remastered, the first thing you notice if you have played it prior on the PS2 is that the game runs smoothers and the game still look beautiful, or even more so better on the PS3. But bsides looks everything is the same, except I believe they added slow motion last kill on each of the colossi battles, (when you play the game you will understand)
With ICO, this was the first time I have played the game, and I must say I ws impressed yet again by an other game by Team ICO. Shadow of the Colossus I believe was a stronger game, but however, ICO still stands as one of the greatest games I have ever played.
If you get a chance to, pick up this collection. I can stress this enough, expessally if you have not played this games. Enjoy!!
