UK video game retailers generated £8.4m in sales last week, according to figures provided by UKIE/GfK Chart-Track (via MCV).
Sega's London 2012: The Video Game was the biggest seller, in a week where only 394,688 games were sold.
It has been speculated that events such as the Queen's Golden Jubilee, the UEFA European Championships and the Olympics have contributed to the lack of sales.
The industry is expected to claw back upwards of £320m over Christmas with titles such as Assassin's Creed 3, Halo 4 and Black Ops 2.
Yesterday, Sony's gaming division revealed that PlayStation hardware and software sales were down for the quarter, while Nintendo recently posted losses for the first time in its history.
