Camelot Unchained aka "Dark Age of Camelot 2" is PvP/building/crafting MMORPG by Mark Jacobs. Some of it's important features are three Realms, 33 different classes (! - but not all will be there by launch), spell collision (say, water + fire produce steam), players crafting their abilities from components and world - made of huge islands - changing it's texture and shape based on player territory control.
100% free form building is another major one - it will matter a lot for the economy and especially for control and defense of conquered territories. Say, this video was made in May by Necromaniak, one of players in alpha tests:
Now, this is rather rough - round & cylindrical shapes, wide choice of textures and some other features are yet to be implemented. Also, buildings will be fully destructible and pillageable -unless built offline or in starting zones.
Besides building, there isn't much footage worth showing at the moment - except for couple screenshots or vines such as this or this. Available videos mostly have 2013 i.e. placeholder models and animations, since the team was focused on building and testing their custom made engine, physics and some basic features till recently. This is major reason for NDA still being on.
