Jak II, while CRAZY difficult at times, was a solid "Action game, platformer" hybrid, but suffered from a couple flaws. Jak 3 fixed some of them. My biggest problem with Jak II was that some of the missions you do (Mainly Krews) seem to have little significance to the plot. With these missions, the plot begins to drag by the end. The game would have been a little bit better without them. Still they don't ruin the game. I love the dessert part of the Jak 3 with the huge vehicles and the mountain temple. Awesome! Haven city has been reduced in size and replaced with the dessert. But the game is is still bigger than Jak II The game is not as long as Jak II but still long enough. I think the story is the best and doesn't drag with excessive missions. The ending is really funny. The difficulty is toned down (THANK GOD) which makes it more enjoyable.
Bottom Line Jak II-good
Jak 3- even better (but not miles ahead of Jak II)
