How do you explain Jak? Think Sonic crossed with Mario - you have your main character - sort of. Well not really, but anyway. You have this cool hero in a platform setting like Mario - BUT the whole setting and the missions are all GTA style. So its this goofy, very fun, arcade adventure, in the open environment type setting that has made Rockstar's GTA franchise so famous. Its really a classic game and worth a pick up at $7.
