The Winterfest 2006 Tournament was a seasonal tournament event during Wintersday 2006 sponsored by ArenaNet. Guilds participated by playing GvG-Battles culminating in a Guild Wars Nightfall only swiss system tournament that offered guilds a chance to win wintergreen candy cane weapons and other in-game prizes. To some degree, the Winterfest 2006 Tournament served as beta test for the future structure of official sanctioned tournaments.
