Wube Software have written up their plans for the future of Factorio and it sounds exciting, with it confirmed that they're looking to work on a big expansion.
Factorio is done, as in the recent 1.1 release is the "final release of the vanilla game" and so will only see standard maintenance patches for bug fixes and alike. The question is where do they take it from here? They went over options like free updates, a sequel and more but settled on doing a big expansion as they're not a fan of multiple smaller DLC.
What to expect from it? Too early to tell they say and they have no idea when it will be ready as work has only just begun. We're looking at likely more than a year.
I would happily pay for an expansion. Factorio is a properly great game and it deserves a long life, and I certainly would love to see even more crammed into an already very busy game.
The post also goes over plenty of stats, showing that Factorio has now sold over 2.5 million copies with over 38 thousand combined years of in-game time from players. That's absolutely insane to think about but not exactly surprising with Steam reviews showing individual players with thousands of hours.
As for jobs, they have a few positions going. Interestingly, on the coding side they mentioned that while they don't need programmers much right now they are lacking Linux/macOS specialists. So if you're strong with both it might be worthwhile reaching out to Wube Software.
