StarCraft BW Remastered actually revived BW in KR.
ASL Season 5 just ended, and there's a big Blizzard sponsored
tournament coming up soon, KSL. All the old players are still owning, Flash, Mind, Shuttl, Rain, Larva.
Starcraft 2 Scene in KR as shrinked, but it's still getting GSL, Super Tournaments, ect. Not that much domination by a single player. The better more competitive scene is outside Korea in the Blizzard WCS series.
WCS Austin just ended, and
WCS Valencia coming up soon. Even if WCS is all foreigners, the level of play is actually pretty good.
