Assassin's Creed Odyssey turned out to be quite the success for Ubisoft. That said, some franchise fans feel like they'd rather go back to the more focused, less RPG-influenced earlier installments.

　　However, Ubisoft CEO Yves Guillemot said in an interview with GamesIndustry this won't be the case as you can have an 'Assassin's Creed Unity' within something like Odyssey anyway.

　　No. 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.

　　Guillemot added that the open world model is sustainable as the market for it is constantly growing. He also discussed the increasingly long tail of Ubisoft titles as a positive factor.

　　It is sustainable, because the world is big and the number of players that can play our games is immense. What we've seen in the last few years is the number of players that play our games is constantly growing.

　　New markets are opening up and games live a lot longer than before. So at the moment we see that we can continue to increase the investments because we know we can have a return on investment that can be quite long-tailed.

　　Our teams don't stop after launching the game. We have huge teams that continue to create content for players to stay in those universes they love to be in. The fact that we have some players buying items in these games is giving our teams the chance to continue creating that extra content.

　　[With Assassin's Creed Odyssey] players got a lot from their investment in the game, a lot more than they got before.

　　Assassin's Creed Odyssey just got its September monthly update, which added the Discovery Tour mode among other things. There won't be a new Assassin's Creed game this year, but the series will return in Fall 2020.
