Wish I had pictures of how well "Player housing" on the world map went for Ultima Online. The entire wilderness as long as there was a 8x8 plot of land without a tree or rock in the way had a house. it looked abysmall and even making the entire multi-faceted world able to contain player housing they litteraly revolved expansion packs around new land for player housing.

Nothing said "great housing implementation" when I logged in my house and had 12 ogres waiting to club my outside because my house blocks there spawn location so they spawn "Outside" my house making it a deathtrap.
