"Welcome to the ‘Top 10’ weekly feature. Each week we will be taking a look at the top 10 selling games in a particular genre, platform, most recent month, even sprinkling in the top 10 selling games from a past year. All sales specified will be worldwide, unless stated otherwise. If there is a particular top 10 you want to see leave a comment and it may be featured in a future top 10. As a note all sales figures are retail only.
This week we will be looking at the top 10 selling PSP games. Last week we looked at the top 10 selling DS games and the week before that the top 10 selling games in 2009."
