I checked this out with a friend, it has some neat area design but still needs work to really be considered playable. The main issues we ran across...
Difficult to see where you are:
~ Needs camera lock around playable area.
~ Needs fade groups for gates, roofs, trees and higher walls.
~ Some areas could use less clutter and/or wider spaces.
For gamemasters:
~ Needs encounter groups for NPCs, so GMs can easily switch their factions.
~ Should raise the arena and make it walkable, so GMs can stage fights there.
Also there are some floating objects.
