I recommend a Emulator if you only want to play one of the
games. Its very troublesome to buy and sell after you finished
playing the game you are interested. However, you can consider
using your PSP as an MP3 player or movie player.
personally i got it cos got a few games in mind to play….crisis
core; FF Tactics, Brave Stroy, Gundams ( Battle Royal, Battle
Tactics), Tales series…...etc…
