Square Enix has recently listed the PS3 version of Nier on the UK Square Enix online store, announcing they have reprinted it in celebration for the launch of Nier: Automata. Due to its low print run and low sales but becoming a cult hit years later it became harder to find at a reasonable price, and with the offering at a low price of £24.99 its a good deal.
Since the PlayStation 3 is region free, if you live in North America and can’t find the game for a low price used copy this could be a good alternative.
