Buy the second one.
Graphics: always one of psp's finest.
Sound: nothing special. Solid
Value: i collected all of the weapons on the first time through the game. I had nothing to go back and do. NO multiplayer. Short story
Tilt: will not keep you coming back for more. Its not that long and you will finish it is 3-4 hours if you are an AVR gamer. Still fun. I guess
BUY THE SECOND ONE! if you were looking forward for Death Jr.
