I've seen many posts saying that the author is still working on it, but those posts were from mid-2015. So now, 2 years later, I'd like to ask if there are still chances that the game will be released in our lifetimes? Bcz if it gets released, I WILL buy it right away, it looks awesome (mainly it's aircraft features)
Yeah they are still working on it.
Updates of the game are usually on the
1st of April. I know it is a weird date, but yeah...
And I think they said it was staying free because it is an open source game I guess.
So you literally know nothing about the game, the only thing you said there that was true was that it was still being worked on.
Very few updates have been on "April Fool's Day", maybe that makes you the fool for saying it.
Furthermore, the game will actually cost, as it's not open source (It's not another clone of TTD, it's one man pouring all his effort into it).
For SPolygon, you can find the pricing structure of the game here
