Grand Theft Auto V

Grand Theft Auto V remains the most commercially successful open-world game ever, with over 200 million copies sold—more than double the sales of #2, Breath of the Wild. Rockstar's 2013 behemoth offers a sprawling Los Santos that feels alive, packed with heists, side activities, and an online mode that continues to draw millions daily. This longevity is unmatched; it's 30% more active in concurrent players than the average open-world title from the same era, and its continuous updates have kept it relevant for over a decade.
