Question 1

Is 0 A.D. free?

Accepted Answer

Yes, entirely. 0 A.D. is open-source under GPL-2.0 with no purchase, subscription or in-game spending of any kind. It is funded by donations to Wildfire Games.

Question 2

Is 0 A.D. finished?

Accepted Answer

It is formally in alpha and has been for over a decade, but it is stable, feature-rich and content-complete in practice. Most players will not encounter anything that feels unfinished. The label reflects the project's own standards rather than the actual play experience.

Question 3

Is 0 A.D. better than Age of Empires II?

Accepted Answer

Age of Empires II: Definitive Edition has more civilisations, a ranked matchmaking service and decades of balance refinement. 0 A.D. has better visuals in places, deeper historical detail, and costs nothing. If you already own AoE2 it remains the more polished competitive game; if you do not, 0 A.D. is a genuine alternative rather than a compromise.

Question 4

How many civilisations does 0 A.D. have?

Accepted Answer

More than a dozen playable civilisations spanning 500 BC to 500 AD, including Athenians, Spartans, Macedonians, Romans, Carthaginians, Persians, Mauryans, Kushites, Gauls, Britons, Iberians, Seleucids, Ptolemies and Han Chinese.

Question 5

Does 0 A.D. have multiplayer?

Accepted Answer

Yes, with an in-game lobby for finding and hosting matches. There is no official ranked ladder, but casual and organised multiplayer both happen regularly.

Question 6

What are 0 A.D.'s system requirements?

Accepted Answer

A 2 GHz dual-core CPU, 4 GB of RAM and an OpenGL 2.1 GPU as a minimum, with roughly 3 GB of disk space. Large late-game battles benefit noticeably from a faster CPU.
