I think the PlayStation Portable AKA PSP is one of my favorite consoles as I had it back in the days. I didn’t have a Vita till now. I could buy a PS Vita PCH-2016. I was suprised by it’s features. I have to say playing some hours on it I found it more playable than my Nintendo Switch. The controls are feeling more accurate and to the point of the Vita. Even if I play Sony Playstation 1 or PSP games like Gran Turismo it was a pleasure on the Vita.
