Grand Theft Auto 5 (GTA 5), one of the leading open-world gaming titles might end up being 2013's highest selling game titles, according to the recent sales figures recorded on a global level. Rockstar, GTA 5's publisher, reportedly sold the game worth $800 million on the day of launch.

The figure is said to exclude Japan and Brazil where GTA 5 is due for release. However, this has marked the highest sale for any game till date according to what Rockstar estimates. With this, Activision climbs down to second spot with sales of $500 million for its Call of Duty: Black Ops 2 in 2012. Activision's CoD: Modern Warfare took five days to reach $775 million worldwide.

"All of us at Take-Two are thrilled with the initial response to Grand Theft Auto V. Once again, the team at Rockstar Games have outdone themselves, setting the entertainment industry's new standard for creativity, innovation and excellence," Take-Two CEO, Strauss Zelnick told CVG. "We are incredibly proud of Rockstar Games' creative achievement and could not be more pleased with the success of this launch."

GTA 5 also broke records in UK and has been proved to be the biggest launch in history. Out of the global $800 million generated by Rockstar, a big chunk worth £65 million came from UK alone. A total of 1.57 million units of GTA 5 have been sold on the day one, according to UK Chart Track Figures, reports CVG.

This also smashed the previous records of Activision's Call of Duty: Black Ops, which sold 1.41 million units, generating £58 million in its launch day in 2010 in UK.
