Kerbal Space Program’s ‘Build Fly Dream’ video is still the best fan-made trailer ever

Almost five years ago, Kerbal Space Program mod creator Shaun Esau uploaded his own trailer for the space-flight simulator. The video recently hit 1 million views on YouTube, and I still consider it one of the best gaming videos on the internet.

Kerbal Space Program is a physics-accurate rocket-science game where players must build vehicles to leave a planet to complete missions. It debuted as an unfinished beta on developer Squad’s website in 2011 before launching into a 1.0 release state in 2015. Last year, publisher Take-Two acquired Squad and Kerbal, and now the game is about to get its first expansion. But through all of that history, no video has captured the story of Kerbal’s gameplay better than Esau’s “Build Fly Dream.”
