The team known as "Ninjas in Pyjamas" has a made a documentary showing off its bomb-planting tactics in Counter-Strike: Global Offensive at Copenhagen Games 2013. Well, it's not so much a documentary as it is a well-produced video of pro players laying down the heat against other teams, but it's still a pretty good way to spend 18 minutes.
If defusing bombs isn't your thing, Copenhagen Games also offers tournaments for StarCraft II, League of Legends, and other competitive multiplayer games. It's always fun to see how people who train for a certain game play compared to casual players, and then quietly sob in a corner after being awed by their skills.
If you said "They aren't that good ," while watching the video, Copenhagen Games will return next year between April 16-20. All you need are some decent teammates, sponsors, and ruthless tenacity.
