I played soccer almost every Saturday between September 2011 and July 2012. We haven't played since then.
I don't know why people stopped showing up, but I can say it was one of my favorite things to do. The players were mostly foreigners (mostly English teachers), largely British, with a few Korean regulars, too. Most of us were not very good (a few were), but no one minded. It was all in good fun, and spirits were always high: Whoever showed up would play. Sometimes it was more than 20 people, sometimes fewer than 10. Always enjoyable, to me. I have good memories of these games.
We played in the easternmost neighborhood or Incheon, called Bupyeong, at a middle school maybe halfway between the recently-opened (as of November 2012) "Samsan Gymnasium" and "Gulpo Stream" subway stations (삼산체육관역 and 굴포천역) [Map]. I walked there from my home in Central Bucheon, 40 minutes away on foot, across Lake Park. Here is a map:
If you click on the "Satellite" version of the map and you can see a big lake to the east. That is "Sang-Dong Lake Park". I walked through it every time I went to play soccer. My home is off to the east, not far. Seoul is off further to the east, if you zoom out.
