Similar to the PlayStation, this console is primarily intended for solo players. If you are looking to play with friends, on holiday for example, turn rather to portable consoles such as the DSi, otherwise, the PSP Go should please you. The main flaw is probably incompatible with the UMD cards. So if you already have an older PSP model, you can not use your old games as they are now dematerialized. However, the PSP allows for example the control of the PS3 remotely, as you have a WiFi connection.
Positive side, the PSP screen is of excellent quality with vivid colors and good resolutions. The games also have good graphics for such a small console. The grip is a little weird at first, because the buttons of the PSP come down but we made it easily. You also played the game "Minis" PlayStation, often funs and cheap.
Finally, good portable console if you play alone, but not recommended if you have a PSP with games on UMD.
