Can you clarify please how and where on Andy were the tournaments undertaken? Were these events, assisted by the GMs a recent thing or from some time ago?
Mostly these were forum-driven events (still, there were ingame notifications as well).
How - classical knockout system;
Where - unless I am mistaken (cause ,myself, I am not interested in such events at all so I didn't visit) and judging by some screens right by the Star gates in the peaceful zone of Andy;
Yes the tournament was organized and moderated by GMs
Time - quite a long time ago (over a year, i think).
Anyways, if players would like some competition - I think it's a good idea to take matters in their own hands - I believe that Aleriana will gladly help with it if she is provided with a concept.
