The PlayStation Portable was a handheld console released by Sony in 2004. This console was great during its time since smartphones weren't used back then (people were still on flip phones lol), and you can play with this anytime, anywhere. Especially while travelling or outdoors. I've played a lot of games with the PSP, most notably MGS: Peace Walker, GTA: VCS, Silent Hill: Origins and Resistance: Retribution. I even modified it to play PS1 games before lol.
