2.0 GB
The loudest thing in the room is usually your own bad decision.
Thief™ Gold is a free arcade game released under Commercial · DRM-free purchase. It runs on Web, Windows, needs about 2.0 GB of disk space, and requires no account, payment or trial. On a computer, the fastest route is the PlayBound Launcher. On a phone or tablet, use the official store or site instead.
One-click install
PlayBound fetches the official release — no third-party mirrors.
Windows
Download the DRM-free Thief Gold offline installer from GOG. GOG Galaxy is optional; the offline installer is sufficient.
Windows
Run the installer, launch Thief Gold once, and set resolution, audio, and controls before beginning the campaign.
Windows
For fan missions, install AngelLoader in a writable folder outside Program Files, then point it to THIEF.EXE and a separate folder containing your mission archives.
Windows
Keep fan missions zipped and let AngelLoader install them. Use “Play without FM” whenever you want to return to the original Thief Gold campaign.

No. Thief Gold is a paid commercial classic. PlayBound lists it as a low-cost master copy, and the GOG offline installer does not require Galaxy.
It includes the original campaign, three additional missions, updated levels, and connective changes, making Gold the definitive release of Garrett's first adventure.
Controller support is possible in the modern GOG package, but mouse and keyboard remain the clearest fit for precise arrows, leaning, and the original inventory interface.
Use the NewDark-compatible GOG build with AngelLoader. Install AngelLoader outside Program Files, point it to THIEF.EXE and a mission folder, and leave downloaded archives zipped.
