My guild (Left Hand Path on Wiccana) constructed our Keep last night. It's the first building for our PvE Guild City and the prereq for most of the other construction later to come.

One thing that has stuck me is the sheer size of the Keep and our surrounding plot of land within an even larger zone. The scale of the thing is astonishing.

Some things to note:

• Buildings cannot be placed just anywhere, there are pre-determined lots, although you can choose "Thieves Guild on this lot, Armorsmith Shop over there" etc..
• There are three city areas within our zone map. As more guilds book their plots the zone is instanced. Right now, Funcom is restricting travel between these guild city instances probably to give players a chance to build first. So no visitors to our guild city yet.
• The guild city zones are actually shared between city building and resource collecting, which is very convenient and lends for some busy activity nearby.
• These are PvE zones, even on a PvP server the buildings cannot be damaged. PvP Battlekeeps will be in a corresponding PvP zone and take a much larger effort to construct.

I love this stuff. It has a lot to do with Age of Conan being my MMORPG of choice. I'm helping construct a city in a world that's enthralled me.
