First off jak 4 entirely there is already hundreds of great bloody fighting games but only one amazing adventure series and its called Jak and Daxter, plus just imagine a multiplayer story mode for ps2 and ps3 where baron praxis daughter (second daughter) forms a army of red krimson guards does a sneak attack on the wastelanders and blows up the monk temple and the wastelands seek refuge to the haven city (with there cars) and you fight side by side with daxter to accomplish something that hopefully naughty dog will come up with..
Don't need to vote. The next game will be Uncharted 3, lol But even if it weren't, I'd certainly pick it. Jak already had it's fun in the sun with 4 consecutive games and 2 spin-offs. At least give Uncharted a trilogy before you go back to Jak.
