Today marks the 7th anniversary of the North American PS2 launch. Many gamers consider this their favorite console. The system totally dominated its generation, ushered in Ebay scalping, and launched with a lackluster library. Its unlikely that its successor will be as successful. I was a college sophomore when it launched and I did not pick up a system until 2004.
My favorites on the system: (Not ranked)
MGS2/3
FFX
Shadow of the Colossus
ICO
Rez
DQVIII
