0 A.D. and OpenRA are the two best free real-time strategy games, serving different tastes. 0 A.D. follows the Age of Empires tradition — slow, historical, visually ambitious, a 3 GB install. OpenRA rebuilds Command & Conquer and Red Alert — fast, retro, 350 MB, with an active competitive ladder. Both are free and open-source with no monetisation.
The two strongest free RTS entry points, and they are not really competitors — they descend from different traditions and reward different instincts. If you are choosing a first free strategy game, this is the decision that matters.
| 0 A.D. | OpenRA | |
|---|---|---|
| Lineage | Age of Empires | Command & Conquer / Red Alert |
| Setting | Bronze and Iron Age history | Retro-futurist Cold War |
| Pace | Slow — long build-up, decisive late pushes | Fast — matches can end in minutes |
| Economy | Villagers gathering from resource nodes | Harvesters and refineries |
| Download size | ~3.0 GB | ~350 MB |
| Visual fidelity | High — rivals commercial releases | Modernised sprites, deliberately retro |
| Ranked play | No official ladder | Active competitive ladder |
| Development status | Formally alpha, playable for years | Stable releases |
You loved Age of Empires, you want a slower game where the build-up is the point, and you have the disk space and hardware for a visually ambitious title.
0 A.D. is an unusually ambitious free RTS that can stand alongside commercial strategy games on its own merits. Huge armies, distinct civilizations, meaningful economies, multiplayer, and extensive modding make it an easy PlayBound recommendation.
OpenRA scratches a very specific itch: remembering how much fun old Command & Conquer was, without having to treat a 1990s PC like a museum exhibit. We picked it because it doesn't merely preserve those games, it understands what made them fun and gives them room to breathe. The result feels familiar within seconds, but the modern controls, multiplayer, balance changes, and community creativity make it surprisingly easy to get hooked again.
