Watch Dogs Legion is the third entry of the open world hacking-themed IP created by Ubisoft at the very beginning of this console generation (though the first installment also shipped on PlayStation 3, Xbox 360, and Nintendo Wii U). Despite some controversies (chiefly the now-infamous graphics downgrade of the final version compared to pre-release trailers), Watch Dogs quickly became a huge intellectual property for the company, breaking several sales records from the get-go, including best-selling Ubisoft game on launch day and best-selling new IP ever in the United Kingdom for its launch week. Before the end of 2014, the game had sold over 10 million units, therefore paving the way for a sequel, which promptly arrived in stores only about two years and a half later.

Watch Dogs 2 managed to address several of its predecessor's shortcomings, expanding the hacking toolset at the player's disposal while delivering a more fitting and endearing cast of characters. However, despite the critics' approval, sales were much lower and Watch Dogs 2 only got to that 10-million milestone by March 2020, taking much longer to sell the same amount.
