Do you know what's better than Grand Theft Auto? Grand Theft Auto in the palm of your hand =D
Gameplay: Pretty much you can do anything you want from chopping off this fat guy's head with a samurai sword to going on a rampage with a rhino tank or if you are a huge pervert get a hooker in your car and watch the car shake. The controls are done well. My only complaint is that the targeting system doesn't really point at the nearest enemy just nearest person. The missions are fun. It may sound weird but even this game has some strategy like when to attack someone so the cops don't notice, or planning an escape route when the cops are after you. This game also has online multiplayer but only ad-hoc (local).
Graphics: The graphics are amazing! They crammed all of Liberty City onto a UMD minus a few places which are under construction. And it still looks great. You can look up into the sky and you can see a plane flying. The buildings actually look different unlike some freeroam games like Spider-Man. And the people actually don't just stand their and do nothing. Occassionally you'll see a cop chasing someone or some mafia guys beating up a cop (rare though) or gangs chasing after you for no reason. The framerate slows down a bit though but not enough to annoy you.
Sound: The voice acting is very well done. The radios are halarious and actually Radio del Mundo has real songs like they seriously put in an Egyptian musician's song in there. My personal favorite LCFR has very funny dialogue but each of the stations are pretty short and will repeat after about half an hour. Another complaint is that sometimes the F word is used a little too much. Yea I know it is an M game but it gets annoying to hear like let's get the F outta here for the 10th time.
Value,tilt: If you have a PSP and you like GTA you need to buy this game. Now you can get it for $20 or less so I strongly recommend this game.
