Here's a phrase you won't read often: after two years of constant feedback from paying customers and excited fans, a new game is ready for launch. That's exactly the situation for Kerbal Space Program, a game that has sold tens of thousands of copies, caught the attention of two space agencies, and earned a hundred thousand fans on Reddit before release.

Kerbal Space Program began as a pet project for Squad, an interactive marketing agency based in Mexico City. Kerbal's creator, Felipe Falanghe, started with an idea for a simple rocket-launching game. After picking a few components, players would launch and see how high they could get before the surly bonds of gravity brought them back.
