Highly recommended for any God of War fan.
The gameplay changed a little from the first game on the series, but it's pretty good and uses the PS3 controller quite well. I can imagine that this game would play just fine with the PSP controls, but I have to say that the additional thumb stick is a must for me to enjoy this title. Sound is pretty good and this game does require quite some skills in order to defeat each enemy, they all have different dynamics and radius that you have to be working with.
Overall this game it's just as impressive as the console material, and very little compromise was made in order to make it fit to the PSP. This PS3 remaster version plays pretty well and has Trophy support. There are a few annoyances when you play this game, specially on segments that when you die, you need to go through cut-scenes and long walking portions before getting to the action. Not too happy abut these portions, but it's a minor complaint. This game is highly recommended for any God of War fan.
