Ubisoft are well known for open world adventure games such as the Assassin's Creed or Watch Dogs series, and the company have now confirmed they'll be doubling down on this strategy according to an interview with GamesIndustry.biz.
CEO Yves Guillemot confirmed that the company will now be focusing on large, open world adventure games such as Assassin's Creed Odyssey, an absolute mammoth of a game, and that's before we get into the DLC.
Our goal is to make sure you can have a Unity within an Odyssey, if you want to have a story of 15 hours, you can have it, but you can also have other stories. You live in that world and you pursue what you want to pursue. You have an experience, many Unity-like experiences.
There are some that may argue that longer is not always better when it comes to games, though. Sometimes gameplay can become repetitive, and that's been a hit and miss issue for Ubisoft in the past.
That being said it seems that Ubisoft are aiming for bigger and bigger stories and content with their games. Watch Dogs Legion will be the next major game to release from the studio, and it'll be interesting to see just how much bigger the game will be compared to it's predecessors.
