I have to see the Mainzframe discussion ep2 and ep4, lastly have talked about Annoverse will build on VR.
Link: Union Update - Annoversary Weeks, Mainzframe & Community Spotlight - Anno Union (anno-union.com)
For All Player: please vote poll on above for Anno developer see.
Now, I still don't own a VR headset. But my good advice is Annoverse should release more on other OS/Platform/Console to increase more player play Anno online.
