21st of October, let’s go!
Available on Steam for wishlisting now as well.
Not sure I agree with having the expansion on the same cost as the base game, but it is a tremendous amount of changes and improvements, both in the free patch as well as the additional paid content. So I’m definitely going to buy it.
I don’t remember when Factorio was in early access. But I can see in my steam purchase history I bought it 1. Sep 2017
