Ultima VII: The Black Gate is the seventh game in the Ultima series by Lord British, aka. Richard Garriott and the first game in the Guardian Trilogy. It brought a whole new level of interactivity to the game world, allowing the character to move everything that wasn't too heavy for them, as well as use items together to create new items, eg making freshly baked bread from self picked wheat, grinding it to flour, mixing the flour with water and then baking it.
