Publisher Ubisoft says it may make Watch Dogs an annual franchise, but it will first take its time on Watch Dogs 2.
The firm's CEO Yves Guillemot told MCV at a roundtable event that the first Watch Dogs has smashed its expectations commercially, and that it is looking to improve the title wherever it can.
But it won't rush out a sequel.
"To start with we will take time on Watch Dogs 2, to make sure – like with Assassin’s Creed II – we can come back with something that takes full advantage of what everything we created to do with the first game," said Guillemot.
"After that, we will see, it depends on our teams. What we try and do is have different teams that take care of a brand, and give each team enough time. So I can’t say now if it will be an annual release, we will see in time how it works out depending on the overall ability of the very talented teams that look after the brand."
He added: "Watch Dogs did a lot better than we expected sales wise. And we are still tweaking some things in the gameplay in some areas. We have built some tools and processes that could make it a huge brand for the company. And the subject of hacking is endless in possibilities, so we think there’s big potential to astonish people in the long-run."
Watch Dogs was the fastest selling new IP in the history of the games industry. And is part of a major year for Ubisoft that includes The Crew, Far Cry 4, Assassin's Creed Unity and new Just Dance properties.
