Like what? I mean, lots of people say this, but while they are happy to say what they don't want there aren't a lot of examples of what they do.
A few examples for sandbox adventures I'd like to highlight:
- Isle of Dread (BECMI D&D)
- Frandor's Keep (HackMaster)
- Doom of the Savage Kings (DCC RPG)
- Thieves of Fortress Badabaskor (OD&D/D&D3e)
- Death on the Reik (WFRP)
Many classic D&D modules are also standalone, location based adventures without intended script or player behaviour. There are places, people, conflicts, you drop in the PCs, and see how it unfolds - the story writes itself and evolves from player action.
