Nice to hear from you again ol mate. I am running around in Istaria myself these days and also having a blast. Perhaps we will run into each other as soon as the transatlantic servers/accounts are open.
Addice: Dont know of any plans to open up for PvP in Horizons yet. Cant see how that is gonna be unless they open some arena, because we are all on the same side here. Personaly I dont like PvP, so if they never implement it, ill be just as happy

Cooporation is the biggest queword in this game. Crossguild cooporation to get certain buildings and structures buildt up so to open up other play areas, building citys, bridges etc. All of these projects need team work at a great extent. Cant see how PvP can be implemented into this other than in some sort of arena. There is a roman cirkus kinda arena already buildt, so with some game tweaking they might turn it into a PvP area.
