I go back and forth on this one. On one hand, it does not really add anything and for a long time I did not really use it. There isn't much point without an appearance system (or a more crucial one). ...
As a low end player, I need to stick to houses with few to no clutter. But as somebody who loves realism and is artistic, I prefer those with clutter. I'm caught in the middle but most of the time, I'm function > form. There's good amount of clutter then there's too much clutter.
