Post - Season 7 World Championship
Gen.G, back then known as KSV eSports, acquired the 2017 League of Legends World Champions Samsung Galaxy's roster. The acquisition happened on the 30th of November, 2017.
Wraith and Stitch left the team. Wraith went to join Jin Air Greenwings and Stitch went to join the LMS team, G-Rex. KSV eSports came into the LCK 2018 Spring Split with their world champ winning roster. Former KT coach, Lee Ji-hoon, joined KSV eSports as the general manager. Through the assistance of Wraith and Jin Air Greenwings defeating the ROX Tigers, KSV eSports managed to qualify for the LCK 2018 Spring Playoff. They met SKT in the wildcard match and conceded defeat with a score of 1:2, thus ending their Spring Split run.
On the 3rd of May, KSV eSports rebranded to Generation Gaming, better abbreviated as Gen.G. Gen.G acquired 2 new players, Fly and MONG. Gen.G qualified to the LCK 2018 Summer Playoffs and ending their regular season with 13 wins and 5 defeats. They were in a 4 way tie with kt Rolster, Griffin and Kingzone DragonX, due to head to head records, Gen.G was fourth. Gen.G were defeated by Afreeca Freecs in the wildcard match, hence putting them into the Korea Regional Gauntlet. Gen.G ran through the whole Korea Regionals Gauntlet by defeating SKT 3:2 and then proceeding to beat the favourites and Summer finalist, Griffin in a 3:2 fashion. They proceeded to defeat Kingzone DragonX dominantly 3:0. Hence empowering the meme of Gen.G's roster being the Gauntlet Gods. Gen.G came into the 2018 Worlds off one of the best gauntlet runs, with the homecrowd backing them up, they failed to show up and ended the group stage with 1:5.
On November 15, Ambition and Crown leaves Gen.G. Ambition retiring and Crown at the time was a free agent, only to join OpTic Gaming in the NA LCS later in the year. On November 17, Mong, Haru and CoreJJ leaves. Haru eventually joins SKT and CoreJJ joins Team Liquid.
On November 23, superstar jungler Peanut joins the roster.
On December 3, Roach joins the roster.
The team competed at the 2018 LoL KeSPA Cup with the new roster and dominated the other teams. They met Griffin in the finals but ended up losing 0:3.
Gen.G came off from a hot streak after the 2019 KeSPA Cup Finals against Griffin. The team failed to qualify for the LCK 2019 Spring Playoffs and just barely avoiding relegations. They ended their Spring regular season with 5:13 record, finishing 7th place.
