I am certain anyone who frequents this forum would have won this event. I'm just a casual player and I came in second 3 years in a row. I also beat the guys who won it all in the round robin stage. It's kinda hard to find great competition when only 3-6 people in the whole country can be bothered to participate... and maybe 100 total have even heard of the game.
"All Korea Championship -Seoul, South Korea -? -2015" NOT DEFUNCT! This event returned in 2016 and 2017. I moved to the US in 2018 but I believe this is still going. The biggest event had only 6 people. Not too many Tecmo fans in Korea, but I can at least say I am 2nd best in a whole country... haha.
