With the release of the PSPgo and a move away from the UMD format in favor of digital distribution, 2009 was a transitional year for the PSP platform. Still, amidst all the growing pains, Sony still managed to get some very high-quality games on their evolving portable platform. Here is our favorite!
Best PSP Game
Patapon 2

Patapon 2 served as a case study for SCEA, which released the game in North America exclusively as a digital download, ahead of the pending release of the PSPgo. Digital downloads of PSP games have since become far more ubiquitous, and while we've still got a long way to go before we reach a download-only future, but Patapon 2 was a significant step for the platform. Add a $20 price tag to all of this and you've got a real attractive package in Patapon 2. It's cheap, it's charming, it's challenging, and it's the type of game you can play for stretches ranging for five minutes to hours. These are all exactly the qualities we hope for from the platform, and it's why we're happy to name Patapon 2 our 2009 PSP game of the year.
