I don't see it as unrealistic, rather like using different scales for the different type of areas. If the size of a room in the grid is 100x100 m, the roomsize in the city/island would be perhaps 10X10 m and inside a house maybe 3x3. The detail level of the rooms would also vary in the different types.

To me it is more about playability than realism. A grid is per definition repetitive and pretty boring, by changing the scale you make the world more interesting for the player.

But we are straying way off the topic now, perhaps we should carry out this discussion somewhere else.
