Yeah I realized the screen dimensions weren't that of PSP format right after I posted it, but there's no way GTA3 looked like that 
Err, the PSP game looked better than GTA3 (improved lighting on cars and the environment).
That shot is 640x448 as well (the typical PS2 resolution).
Furthermore, the shot was taken from an archive from 2001 on Gamespot. So, unless they jumped 5 years into the future and captured a non-16:9 shot from the PSP, I think it's safe to say that what you are seeing is a PS2 shot.
Crackdown was a limited experience, but a smooth running one.
It was also boring and repetitive. Couldn't stand that game. Interesting concept, but the actual game design is terrible. Running around the city and climbing tall builds is fun initially, but that grows old quickly and missions fail to make up for it. Collecting those power spheres was more entertaining than the actual missions (and that's not really a good thing).
