Pursuit Force for PSP is a good game on a certain level.
The graphics are pretty damn good, the textures are really good for this game, and the sound is good.
The gameplay is pretty solid and it's the first game in which you can leap from car to car on PSP.
However, for this game you have to be really good at it, the game is hard and it gets harder everytime you pass a level.
As for glitches/bugs in the game I did find one, when i crashed into the wall on one of the highway levels I went through the wall, and was driving outside of the level.
the gameplay gets repetative, so if you like something new every time like GTA etc, then this isn't what your looking for, the gameplay does not have longetivity in my oppinion, it's not a game that will give the player a long term of play.
