Ubisoft has discussed a big-budget future similar to Assassin's Creed for I Am Alive.
Creative director Stan Mettra told Digital Spy that it had to "pull back" from the original scope of the project, which saw players explore a destroyed city days after a devastating earthquake, which it hopes to explore in future games.
"We choose to pull back in time to one year after, to not have to really deal with some things that are really hard, you know, police on the street, riots with thousands of people, and the previous game didn't have that, and that was a problem," said Mettra.
"That costs... I mean, maybe later we get the chance to do something like that if the people like this game, they want to expand and can show more of this."
When asked whether this could be through DLC, Mettra replied: "Not DLC. We're talking about something that is as expensive as Assassin's Creed, or these kind of triple A games, very high production. Teams with several hundreds of people.
"And that's not what we have here. We have something more intimate, human-centric. This will be the price of a downloadable game, there's not going to be a surprise. It's really a digital game but with a larger scope than ever before."
He later added: "I mean if people like [the game], we can continue, taking that human behaviour and all the gameplay, strategy gameplay, that can be taken from it. We'd love to do it."
