Any games with "endless" world maps?

I was just remembering how impressive the system used in The Elder Scrolls Morrowind was, where you could walk forever in any direction and never come to the "end of the world" wall. It accomplished that by making the world out of seamlessly joined grid of square maps which were loaded or generated as the player entered an area. If you walked to the edge of the continent in any direction, you came to the coast, then islands, then finally just endless ocean- but still no "end of the world" wall or instant death event like other games usually use to contain players.

Since you could make new islands/continents anywhere, you could expand almost endlessly without having to "teleport" to new areas. That added a lot to the sense of immersion.

Does anyone know of other games that had "endless" auto generated game worlds?
