The EVE DUST Summerfest runs this weekend, September 14th-16th, in Loutraki, Greece. It's followed shortly by the Tokyo Game Show on the 20th-23rd. The player-organized VETO EVE event is in London on the 29th, so if you're in town for the Eurogamer Expo, which runs from the 27th-30th, you might as well check it out. After that, the party moves to Igromir in Moscow, Russia before winding up in the Las Vegas for EVE Vegas.
