I own every SSX game available on every platform. For me, SSX3 for the PS2 is truly exceptional.
I love the different types of game play though the full peak challenge while conquering the mountain is my favorite. The long runs though the backcountry are such a rush.
While I enjoy the advancement of the controllers (Shaun White/Wii Fit/Tony Hawk The Ride) to provide new exciting interactions with our games, I still miss the rush of that first 100 hours of playing SSX 3.
Everyone involved in SSX 3 will always be a hero to me. Wish I had taken the time back in '03 to write them a thank you letter or something, but I just couldn't put the controller down.
