oolite

A sandbox universe lets players pilot spacecraft, trade goods between star systems, and engage in ship‑to‑ship combat. The game simulates a persistent galaxy with dynamic economies, allowing users to explore, mine, and complete missions while managing cargo and reputation. Its open architecture supports a wide range of ships, weapons, and planetary environments, providing a flexible setting for both casual and strategic play.

The platform is built for macOS and is released as a stable version, with a development community that contributes extensive expansion packs. More than a thousand community‑created add‑ons are available in two formats: the newer OXZ packages, which the game can download and install automatically via a “Manage Expansion Packs” menu, and the older OXP packages, which require manual installation but are easier to modify. Documentation, bug tracking, and discussion forums are hosted on the project’s website and GitHub.

Users range from fans of classic space simulators to developers interested in extending the game’s content. The expansion system encourages customization, while the core gameplay focuses on navigation, trade routes, and combat mechanics within a self‑contained, sci‑fi setting.
