yes this game is active. It's hard for a humble gamer to say which server has the largest population as that would mean playing on all servers !
It is probably on German servers that you will be able to find the largest communities. The French server and the Spanish server are still playing, but they are now small communities. EU servers have larger communities. I think the Polish server also has a good community.
Game Forge said a few weeks ago that they plan to merge some servers with small communities, but we don't know which servers are affected. We would like to have the information, this is the opportunity to ask the question again !
Hello community master which servers will merge and when ? No tongue in cheek, answers !
Finally there are two new servers Svidur (EU) and Kerub (DE) where a lot of players are trying their luck at the moment. These two servers were opened a month ago.
