I would like To say I'm well balance but I tend to go back and forth between style and function. I'd say I weigh more into style than Function.
Above all I try to put in a lot of detail of my builds, more so for authenticity, and Most of the time they end up working out... sure the Load time is long but it's playable. But if it ends up not working out I rework it.
For example Currently into Castle Building, and my Castles have Walls, with Turrets, a Gate House, Posterns, Dungeons, Vaults, throne room, Library, Mage's Study, King's Study, Knight's Hall, Swimming Pool/ 3 Bath Chambers, and Several Bed Chambers.
Now. I would say I use about 60%-70% of those areas in my castle, and almost everything is accessible.
Until acouple of days ago I had the King and a mage try to go to their bed chambers, and they couldn't climb a Stairway, which was annoying so I had to rework the entire Main Tower. The Prince's Bedroom, the Mage's Bedroom and the King's Bedroom all had to be rebuilt.
