The little PSP is like an old trusted friend with me owning it more for as an add on to the PS3 than anything else. However without realizing I am swamped with some fulfilling titles which have dragged me kicking and screaming away from my PS3.
If you get chance or for any reason missed these the first time round, search these games out as they are dirt cheap either in the Pre Owned Section of your local games store of check out the predictable EBay for a bargain. Adventure hats at the ready, give them some of your time.
