Amazing Game to Play!
first off i'eve never actually played the other jak games but this one is one of my fav games of all time.
the single player is the only thing u can do but its amazing. u get 12 gun through-out the game and each one is part of a different class
you can unlock 8 differnet vehicles to race, kill marauders w/e u want to do.
What i like most about the game however is how its completely freeroaming
it doesn't force u to continue the game and finish it to fast. which some games may do.
overall it has great single player story mode
great graphics
and a great replay value
once u beat the game u can unlock cheats that u can use to help u complete the game a second time around
