We here in the SIMBL have a great core group of GMS that make the league what it is. We are always looking for prospective GMS to join our world.

You need JavaScript enabled to view it or contact any SIMBL GM for reference. You will be welcomed with open arms and feel comfortable in a non-egotistical or clique-type league that differs from many that are out there.

The SIMBL currently uses the OOTP 22 version with the current patches of OOTP.  The SIMBL as a league converts every other version of OOTP released.

The SIMBL used OOTP 6.5 for the 2005-2015 seasons then made the complete conversion to OOTP 10 for the 2016-2018 seasons.  The move was too big of jump for the game engine changes from jumps from OOTP 6.5 to OOTP 10 and caused many disturbances in the file resulting in unrealistic offensive statistics, number and severity of injuries and the decimation of pitching talent.  Therefore it was voted on by the league to retire the 2005-2018 file, now known as the SIMBL First File Era, but to save all history and statistical records for the league.  The conversion was then made to the OOTP 11 game and a complete new file.  A live draft for the first eight rounds was then completed with a new file and the SIMBL New File Era started with the 2019 SIMBL season.  The league used OOTP 11 for the start of the SIMBL New File Era for the 2019-2023 seasons.

The league converted from OOTP 11 to the OOTP 13 game version on the 2024 off-season date of January 1, 2024.  The league used OOTP 13 for the 2024-2030 seasons.  On the 2031 off-season date of January 1, 2031 and on real-life date June 24, 2014, the SIMBL successfully converted from OOTP 13 to OOTP 15 which was used for the 2031-2039 seasons.  In real-life July, 2017 and before the start of the 2040 season the league converted from OOTP 15 to OOTP 18 and started OOTP 18 play on real-life date July 27, 2017.

After a league vote during the 2048 season, the SIMBL agreed to convert from OOTP 18 to the then-brand new OOTP 20 after two full years of real-life usage of OOTP 18.  On real-life date July 28, 2019 and on the 1/1/2049 ingame date the conversion was complete and the league started using OOTP 20 which is played with the league until the current date.

SIMBL GMs voted long ago and it is now a custom that the league converts only every other version of OOTP that is released.

The SIMBL was founded on September 2, 2006.  The First File Inaugural Draft consisted of some 30 rounds of live drafting via the SIMBL Message Board and lasted approximately three and a half weeks.  On October 18, 2006, exactly one month from the founding of the league, the first SIMBL SIM was run for the beginning of the 2005 SIMBL season and the league hasn't stopped simulating since playing three times a week with a couple of delays due to upgrade conversions of the game.  The SIMBL has proudly maintained a 75%+ career export rate for all of the GMs who have participated in the league past and present which is in itself a representation of the way the league is enjoyed and savored by its participants.

The league built it's history and used the original OOTP 6.5 First File for 11 seasons for the 2005-2015 seasons.  After the 2015 season the choice was made by a vote by the league to convert to the new-at-the-moment OOTP 10 using the same original file.  This decision was made mainly to keep the SIMBL available to GMs in the OOTP community who mostly had moved on long since from the OOTP 6.5 game.  The SIMBL was one of the very last thriving and successful OOTP 6.5 leagues not using an updated version of the game which SIMBL leadership didn't want to be a handicap for the league finding active GMs for league participation and GM turnover in the future.

The conversion was made and OOTP 10 was used for the 2016, 2017 and 2018 SIMBL seasons.  During those seasons, the league found out that such a huge jump in games from OOTP 6.5 to OOTP 10 was too much for the file to take.  The differences between the 6.5 game and the entirely rewritten game engine of OOTP 10 eventually caused the league to suffer an outrageous and unrealistic increase in offensive numbers, ratings, talent and power (resulting in several 'false' new team and individual offensive records being set) and also caused decimation to pitching talent and increased the severity and occurrence of injuries, and the ratings depletion due to them, mostly to pitchers.  The 2016-2018 seasons are known now as "The Steroid Era" of the SIMBL's history and a conversation continues to this day involving on whether records broken and set during these three seasons should be honored or not and also if an asterisk should be placed upon them due to the 'borked' file that was used during those seasons.

The leadership of the SIMBL and its GMs tried in vain to allow the conversion to work but ultimately it was an unsuccessful effort.  The file was considered unrepairable and upon the league vote, the decision was made to retire the 2005-2018 file and at the same time start an entirely brand new file with new players.  With the just-released version of OOTP 11 hitting the market, the decision was also made to not only start a new file but also convert from OOTP 10 to OOTP 11 at the same time.

The SIMBL retired the original file but kept the 14 seasons of history and records archived and converted them to the newer era now known as the SIMBL New File Era.  After several weeks of delay and preparation as a league spanning from real-life May 29, 2010 to June 20, 2010, the SIMBL New File Era Inaugural Draft officially started on June 21, 2010 with a live eight-round draft.  The live draft ended on July 10, 2010 and the rest of the draft, from rounds 8-125, were run by the computer as agreed previously by the league as a consensus.

After more organization, preparation and resolutions, the SIMBL New File Era with OOTP 11 officially started play with 2019 SIM 1 on real-life date July 26, 2010.

The SIMBL played five seasons, 2019-2023, with OOTP 11.  On the January 1, 2024 league date and on real-life date November 19, 2012, the SIMBL successfully converted to the OOTP 13 game version and played six seasons, 2014-2030, with OOTP 13.  On the January 1, 2031 league date and on real-life date June 24, 2014, the SIMBL successfully converted to OOTP 15  in which it used from the 2031 season through the 2039 season.

The league then again converted completely on July 27, 2017 from OOTP 15 to OOTP 18.

After a league vote during the 2048 season, the SIMBL agreed to convert from OOTP 18 to the then-brand new OOTP 20 after two full years of real-life usage.  On real-life date July 28, 2019 and on the 1/1/2049 ingame date the conversion was complete and the league started using OOTP 20 which is played with the league until the 1/1/2056 league date.

After nearly two real-life years and seven more seasons, the SIMBL again converted from OOTP 20 to OOTP 22 during the real-life week of July 5, 2021 and started using OOTP 22 with the 2056 off-season and Opening Day 2056 in which the league currently still uses to this date.

SIMBL GMs voted long ago and it is now a custom that the league converts as a league only every other version of OOTP that is released (every even numbered version).

We will get back to you in a very short time and look forward to competing against you and you joining us in the SIMBL!
