For the Rise of Immortals community team at Petroglyph, there are four primary methods we use to communicate with our community - 1) Website/Forums, 2) Game Interface, 3) Chat/Social Networks, 4) E-mail
The website/forums is number one in importance simply because it
provides both short-term and long-term communication. You can post a
news announcement valid for that specific period of time that anyone can
reference repeatedly through a common link, or something that can be
archived for review months later.
The game interface is next in importance because we can post news
directly on the launcher, in-game ad sections, and send updated messages
to those that are playing a game at that time. The downsize is all of
these areas, particularly one-off messages in chat are time sensitive
and mainly only apply to that moment. This is why I place it second in
importance, as you can always regurgitate news via the website/forums.
And then there's all those social networks, excellent ways to spread the
word about an announcement after it has been established in the game
and main website/forums. Just as important are tools like Skype which we
use constantly for those one-off messages and more personable
discussion between community leaders. Skype is excellent for active
group chat this way.
And last is e-mail, used sparingly every week or two for key
announcements consolidated through newsletters. The best way to reach
older community members that may have drifted off to another game and
need a reminder at how awesome yours is still after that last game
update announced in the previous methods.
