Some PSP games have found their prices increase after the latest PSN update. Something like this should never happen. This is something that Gamestop would do if the demand for a game increased. Though the games that received the higher prices aren't even new. In some cases the game aren't even good, not even burnt sausage good. Gangs of London got bashed by critics, but for some reason Sony thinks it warrants an $11 raise in price. Not every game saw a price change and one game actually got a $10 decrease: The Con. I wonder if Sony is trying to tell us something with that. Anyways here is the list of changes thanks to Kotaku.
