Yeah, so this is a weird thing.
I just got High School Musical 3 Senior Year Dance! for the PS2 (*coughs*) in the mail but... this was a bit strange.
Despite the box being a black label version, the disc inside is
Greatest Hits. It even has the GH bit in the SLUS and everything. Someone has (thankfully) posted scans of the cover and media
here.
The person who sold me the game told me she got it in a dance pad + game bundle. And this is the weird part... I don't think the game even got close to meeting the requirements for Greatest Hits status (400,000 sold copies). I can't find a retail Greatest Hits box art anywhere.
So why does this thing have a Greatest Hits disc?
