International Doom League



The International Doom League (also referred to as IDL) is a private, competitive CTF league played on the ZDaemon engine.

Introduction
The International Doom League is the largest and longest enduring Doom CTF league in the world. The IDL is made up of eight teams, in two conferences, the International Doom Conference (IDC) and the World Doom Conference (WDC) with two divisions each. The regular season lasts nine weeks with an additional three weeks of playoff contention. All teams that win their divisions enter the playoffs as well as an additional wild card team.

The final game of the season is called the MasterBowl, which is followed by a roman numeral denoting the season the game was played in. This is a play on the National Football League's SuperBowl championship game. The IDL draws much of its inspiration from the NFL and other American sports leagues. The two teams which face off are those who won their conference's championship the week prior to the MasterBowl.

Entrance into the League
The IDL is currently an invite only league, not only to ensure that teams sign reliable players, but also those who tend to play at the highest of levels. Players who show a proactive, vested interest in the the league, the game, and the community are those most likely to receive free agency invitations. The IDL free agency has housed representatives from over eight countries so far.

Franchised Players & the IDL Draft
All players that are invited and accept to join the league are placed onto a Free Agency list during the pre-season. Captains and players can come to an agreement to play together prior to the draft. These players are called "franchised players" and cannot be traded or dropped from a roster for the entire season.

Players who are not franchised and/or choose to enter the draft remain in free agency until the live draft occurs. During the live draft, captains choose players for their teams by following a predetermined order. The draft is often quite competitive and strategic as captains attempt to predict and react to other teams' draft picks.

Game Structure
Each IDL game is composed of a minimum of two rounds. A standard IDL round is 3-on-3 at ten minutes each, with a five flag limit. When the time or flag limit is reached, the team with the most flags scored is the winner of the round. If the amount of flags scored is equal, that round is a tie. If a different team wins both the first and second rounds or one of those rounds was tied, a third tie-breaker round is played. At the completion of the third tie-breaking round, the team with the most rounds won is declared the winner of the game. During the regular season, should the amount of rounds won be equal, the game is declared a tie. During the playoff season, tie-breaking rounds are played until a team wins one.

History and League Changes


In the league's inaugural season, eight teams competed in an eight week regular season with three weeks of playoff contentions. During this season, players signed up and captains were randomly assigned to eight teams. Teams only had rosters of three players. Both of these aspects of the league would change in the subsequent summer season to address a number of issues including a rapidly rising interest in the league and to make teams more stable.

For three seasons (Summer 2007 - Summer 2008), the IDL moved to a twelve team format. The first of these seasons saw an eleven week regular season, the longest to date. Starting with the Winter 2008 season, the league moved to the now standard nine week regular season. The Summer 2008 season marked the last time that the league housed twelve teams.

Other notable differences during the first four seasons of the league include open registration and captains being able to name their teams. These aspects of the league changed in Winter 2009, which has been dubbed the beginning of the Franchise Era. Teams are now permanent and players can carry over season to season. This change was made in an attempt to make the IDL function more akin to a true professional sports league.
