Yes, amazing games. When I played the PS2 versions on my PS3, I said that by just upping the resolution would make these games current gen worthy games. IMO even on the PS2 they still look better than anything available on the Wii.
David Jaffe stated they had gameplay ideas for God of War which they could not realize on PS2 hardware and so had to wait for the PS3. God of War 3 is my most anticipated game so far.
