One of our biggest complaints about the PSP Go seems to be partially addressed today as the portable console officially goes on sale. Sony has updated the Go's firmware to 6.10, which introduces a new Store interface and access to a much larger portion of original PSP games.
While the selection of games is still nowhere near complete, some notable titles added today are God of War: Chains of Olympus, Madden NFL 10, Gran Turismo, and MotorStorm: Arctic Edge. Also hitting the store today are PSP Minis, smaller, less-expensive download-only games that range in price from $5 to $10.
Firmware version 6.10 also introduces SensMe, Sony's answer to iTunes' Genius List. SensMe takes a look at your audio library and adjusts playlists according to your "mood."
Though this update is for all PSP models, another noteworthy update that concerns the PSP Go specifically is the ability to tether a mobile phone to the device and use its data network as an access point. While this will only work with mobile phones that allow for such a thing, we can't imagine the speed being any better than what we experienced with a standard Wi-Fi router.
