Kerbal Space Program
How hard can it really be to build a rocket? Turns out extremely, but thanks to Kerbal Space Program it can also be extremely funny. The space flight simulation title bases its building and launching of rockets and other spacecraft off of completely realistic physics. The humorous twist are the titular Kerbals, silly looking aliens who are your guinea pigs. The meat of Kerbal Space Program is its incredibly intricate building systems that challenge you to make effective spaceships, but your many failures are made easier by the presence of the Kerbals at all times. Sometimes you might find yourself making the most failure prone craft you can just to see how it treats your willing victims.
