The best way to sell a PSP in North America these days may be to anchor it to a game like Metal Gear Solid: Peace Walker, as Sony is doing with the latest PSP "entertainment pack."
Sony and Konami are going co-op on the limited edition Metal Gear Solid: Peace Walker PSP Entertainment Pack, featuring a "spirited green" PSP-3000, exactly one copy of Peace Walker on UMD, "special" in-game downloadable content, 2 GB worth of Memory Stick and something else downloadable from the PlayStation Video Store.
It may not be as ornate or trinket filled as the Japanese equivalent, but this is what you get when you don't buy PSP games anymore, North America.
The Metal Gear Solid: Peace Walker PSP pack hits June 8 for $199.99 USD.
