GFK-ChartTrack has confirmed that Fallout: New Vegas has outperformed its predecessor Fallout 3's opening weekend sales by almost a third. The UK games data monitor reported that New Vegas - which went top of the games charts this morning - "comfortably" beat Bethesda's previous record holder. New Vegas' sales on Friday, Saturday and Sunday were 29 per cent greater than Fallout 3's in week 44 of 2008. That game also hit No.1 in the chart.
