I have played Jak 3 for about one hour, and its pretty good.. The new "city" area, umm.. I forgot what its called, anyway its where the outcasts live, it feels much more alive, people walking around and even small animals running around the streets. Remind yourself not to piss the people off, as they now carry arms, hit someone by mistake and he will shoot at you.
No hover cars either, they have been replaced by small reptile looking animals which you can ride.
You cant drive the dune buggy’s in the city, they are only available if you want to drive around in the HUGE desert. The physics of the dune buggy’s are quite good, I have had the pleasure to drive two of them, one a simple race model and the other a more powerful one with weapons. There are lots more available to unlock in the dune buggy depot.
Jak 3 has some of the best graphics I have seen, great lightning, great effects (you should see the sandstorms going in full force, its even better when the sandstorms stops and the sun rays start shining through the sand in the air).. The animations in the cut scenes are better than ever, and yes I have seen bump mapping.. Not only in the cut scenes but also in the game. You can observe it in the desert city by some of the buildings.. Metallic objects have a bump mapped surface.
The game running at a pretty stable 60fps, I have seen some screen tearing though, too bad they didn’t get rid of those. Still 60fps with tearing > 30fps.
I noticed you can trigger Dark Jak on and off whenever you will, so you are not forced to play as Dark Jak for as long as his powers last, like in Jak 2 (think of it as the boost in Burnout 2 versus Burnout 3).
So far Im liking it more than Jak 2.
