Jak 3 is one of the most varied platformers out there, and it's a good close to the trilogy.
Whereas Jak II implemented a whole wack of new features that set itself apart from the first game, Jak 3 stays largely the same. Not to say that's a bad thing, as Jak II was a great game. However, there is one new gameplay aspect in Jak 3 that plays a large role, and that is driving. Seeing as how about half of the game takes place in the Wasteland, you'll be using dunebuggies to traverse across the sandy terrains. They have decent control, but suffer from large spin outs, and the missions including them to tend to be a tad on the lame side. There are also Hang glider, turret and Jetboard missions, including one of the strangest tasks I've seen in a Jak game. (I'm sorry, but killing plants while riding a Jetboard just isn't as cool as it sounds; and it doesn't even sound THAT cool).
Jak 3 has also taken a cue from the Ratchet and Clank series by offering upgradeable weapons. This serves as a cool feature, as opposed to the four selectable guns from the first series, you now have essentially twelve. Some of them are more useful than others, but they all make pretty awesome explosions.
Though the gameplay is a tad on the familiar side, and the new aspects may not add much, the graphics are as crisp as ever. Character models and animations are superb, and the new Wasteland area is one of the hugest places to explore in any platform title. All your favourite voice actors from the last game return, and they do just a great a job as ever. The music in the game has gotten maybe even a little better, and never takes away from what's going on. However, I did suffer from a few occasions where it just stopped playing, leaving dead silence, but perhaps that was just my copy.
As great a job as the voice actors do, they definetley have a weaker script to work with this time. Though it's just as hilarious as ever (the revelation of who was really behind the Precursors had me rolling on the floor) some of the scenes seem to jump around a bit, and certain plot points seem loosely thrown together. You'll also have to have played the other games to recognize certain aspects.
Jak 3's length drawns in at about the same time as it's predecessor, about 10 hours or so. It may take you longer, depending on how many times you may have to restart some levels. Jak 3 is by no means an easy game, but it's not an impossible one. Once you've figured out enemies patterns it's quite easy to get past those tricky spots. Also, the location of checkpoints is much more forgiving than it was in the sequel.
Overall, Jak 3 is a solid game that lives up to being the last part in a terrific series. It's not quite everything Jak II was, and some of the new gameplay aspects fall flat. However, this is also what makes Jak 3 so reccomendable, that it has something for any fan of the Action genre. Fans shouldn't hesitate to pick this one up, and anyone looking for a great gaming experience wouldn't be wrong to either.
