Really, when I was focused on organizing my games by UPC, I hated Platinum Hits. Every other variation of greatest hits kept their old UPC. Platinum Hits adopted a new Microsoft UPC because they were re-released as a Platinum hit by Microsoft, so the games were out of order, and not even same company but later release. Any game that was PH automatically became Microsoft titles, instead of their original publishers.
Now I just hate looking at the mismatched bars on the spines. Why are PH bars so looooong? They could have made it the same length, just in grey, and the front would specify that it was a Platinum Hits game. But no. Microsoft, I guess, assumed no one would keep the box so they didn't bother lining it up.
Otherwise, Greatest Hits/Player's choice doesn't bother me in the least.
