OpenRW is an open-source, cross-platform re-implementation of the Grand Theft Auto III game engine written in C++. It requires a legitimate copy of the original PC game's data files and aims to run the classic 2001 title natively on modern Linux, macOS, Windows, and BSD systems.

Use cases

• play gta iii on linux without the original executable
• run grand theft auto 3 natively on modern macos
• open source reimplementation of a classic game engine
• preserve old pc games for modern systems
• study how the gta iii engine works
• run gta3 with community mods on bsd

When to choose

• you own GTA III and want to play it natively on Linux, macOS, Windows, or BSD
• you want a free-software engine that avoids running the original 2001 binary
• you want to contribute to or study a re-implementation of a classic game engine

When to avoid

• you do not own a legitimate copy of the original GTA III PC game
• you want multiplayer or gameplay modifications, which are out of scope
• you need a fully complete 1.0 experience, as the project is still in active development toward that goal
