The death of this game has been a long time coming and is truly inevitable.
First, the heat death of the universe, something difficult to precisely calculate, will happen in roughly 10^106 years, which I doubt 0 AD will survive.
Even if we prepare for that, there is the more immediate problem of the sun depleting its hydrogen reserves in approximately 5 billion years. Unless our team develops proper technology to survive in space, I think 0 AD will fail.
In a similar vein, the Andromeda Galaxy's collision with the Milky Way in 4.5 billion years may pose a serious risk to the survival of the community.
For these reasons, I regret to say that 0 AD is doomed.
