Intro to PS2

I recently got new controllers and an AV cable for the Playstation 2 console I got as a Christmas gift in 2009. It's the first time it's been played since then, and I've been looking forward to collecting the games I used to have. The ones I have the most vivid memories of are Katamari Damaci (2004), Godzilla: Save the Earth (2004), and Transformers (2004). Those are top priority!
