We choose to play Kerbal Space Program in this decade and play the other games, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the other games too." - President Kernnedy I want to pledge more cash to KSP development.
