In the year 2005, I also got me a PlayStation Portable (PSP) and I loved it right away. Even though it was kind of expensive at first, it's really an awesome little gadget. Other than playing video games, it can also be used for a number of other functions, like storing and viewing images, playing MP3 music and showing MP4 videos, as well as playing UMDs. Below you can see a list of games I own on the PSP:

Daxter	Driver 76	Grand Theft Auto: Liberty City Stories
Grand Theft Auto: Vice City Stories	Metal Gear Solid: Portable Ops	Metal Gear Solid: Peace Walker
SOCOM: US Navy SEALs Tactical Strike	Tekken: Dark Resurrection
