What was your first HD game experience, and what was it like?

I think Christmas 2008 was when I got a HD TV. It looked good. The first game I booted up was Naruto Ultimate Ninja Storm.
Prior to that I didn't really get what HD was. I downloaded some HD background images off the Playstation Store, along with the same background image in SD, but on my CRT TV the only difference was that the HD background looked widescreen.
