First bursting on the progaming when it was just only starting off, he impressed many with his Protoss vs. Zerg play, as well as his many uses of hiding buildings. Playing for Hanbit Stars, winning two OGN Starleagues and being known as the protoss who has revolutionised modern Protoss, he eventually retired, settling onto a life of commentating with OGN for Proleagues and game designing with a company. His last hurrah was during the Panasonic OSL, where, even though he was semi-retired, was able to put on an excellent last stand, especially against the Emperor, SlayerS_`BoxeR`.

GARIMTO won two major OnGameNet Starleagues in Freechal (defeating SKELTON, 3-0) and the Emperor himself in the SKY 2001 OSL, BoxeR (3-2), where the latter would go on to have a tough time in later OSL finals. Besides the OGN leagues, he would rarely appear in Teamleagues for Hanbit or KPGA Tournaments.

After his military service, he decided to return to progaming. He quit his job as a commentator, and signed a lucrative contract with KTF MagicNs. He was listed on the roster as a player, but most viewed him as more of a mentor and a coach. He played once, losing to Free during the 2007 Shinhan Proleague R2 before once again retiring.

GARIMTO is as a vocal member of the Starcraft community with many famous sayings, amongst which, GARIMTO coined the phrase "Sense of Star."

GARIMTO was also very active in the early online Starcraft forums GemQ. During this era, GARIMTO was a part of a vocal faction which included Autumn and H.O.T-Forever. When GARIMTO lost a match to Boxer's hidden double barracks strategy, Autumn critized Boxer for cheesing. This resulted in a series of heated arguments between Boxer's fans and Autumn's faction.
