Because people don't have unlimited free time.

 

I don't expect every PSP title to have complete and perfect data. I was refering to the total PSP software sales. It's not consistent on this site. As I mentioned in the first post, the sales in the game database are greater than 15M for the PAL region, while the total on weekly Others is sitting at 4M.
