One of the biggest events for players in EVE Online is the Alliance PvP Tournament which is held annually. CCP Games' new Alliance Tournament page explains what the event is all about: "The EVE Online Alliance Tournament is the ultimate battlefield in which the top pilots in EVE Online fight for the glory and honour of their alliance. 64 Alliances compete over 3 weekends of intense, explosive action, with the final weekend broadcast live via EVE TV."
Last year's was tournament was a big success, with some excellent commentary on the matches from members of the EVE playerbase and no small amount of drama. Given how well things worked out last year, the 2009 Alliance Tournament will follow the same format, but there are a few changes that EVE developer CCP Claw discusses in his dev blog "How do you stop a man with seven alliance tournaments?"
