Gamespot's claiming its UK network is now at 4.5 million unique users per month, GI reports.
The number's taken from December.
Total page views for the period remained flat at just over 58 million. The figures includes all UK traffic to sister-sites GameFaqs and GameRankings.
"Videogaming is now one of the UK's favourite pastimes with an all time high of 82 million games purchased in 2008 [according to ELSPA], and this is reflected in GameSpot UK's growth", said CBS UK boss Geoff Inns.
"We are delighted to re-confirm our number one spot among UK videogaming sites."
