I beg to differ, allwyn
The PSP has been outshined by the Nintendo DS, which is a more fun gaming platform. It offers dual screens, a touchscreen, more innovative games, and good battery life. The PSP is good, but has too many flaws - the screen, poor battery life, expensive games, etc. Moreover, the DS runs all GBA games and can take a GBA game as well as a DS game in at the same time. You can choose which one to play

Besides, who doesn't love the Mario franchise?

Other good games include Nintendogs, Castlevania, Wario Ware Touched and the upcoming Metroid Prime and Resident Evil DS
And yes, it costs just $130 - you can get one for $130 with Nintendogs or with the new Mario Cart game
