EDGE: "There was no single off-on moment, no switch that flipped. No particular number between one and 499 indicated the six months of sleepless nights spent in Pacific City thereafter, scouring every rooftop, every gangway, pipe and outcrop for that final 500th glowing Agility Orb. Even those who are usually unmoved by the frivolous, timewasting allure of collectibles found their resolve eroded by Crackdown’s method of subtle, gradual ingratiation – a self-destructive habit formed almost without perception during the course of play. Collecting Agility Orbs may have begun as a distraction from decimating drug cartels – one of a number of side dishes in the buffet meal of Crackdown’s crime-ridden open world – but by the time the murderous main course was being cleared away we were licking the plates, fervently gathering up the remaining morsels. Finding Agility Orbs was now the game’s sole function, the crime bosses having been months in the ground as we tracked down the remaining few. It wasn’t mania or obsession, we told ourselves, it was just tidiness."
