I would put most of it on our social network on LINE. Between all 6 guilds we have more than 150 people from all over the world in the Intrim family in our group there. Really helps to have people to talk to literally 24 hours a day.
The feeling of community and friendship binds us together more than the game itself and really helps us to want to keep pushing together to achieve our goals, from the new players in Intrim V and VI to the end gamers in Intrim I and II.
