Kerbal Space Program - Mun Mission Using Only SRB's
Not just any old challenge, but a tribute to the British Interplanetary Society's speculative design for a real life moon rocket published in 1939. ( http://www.bis-space.com/ )
Before anyone asks, it took about 20 tries to perform the landing correctly, you need to cut the power with a margin of about 0.1 seconds, and I'd wasted all my sepatrons on making sure I didn't land on the wrong side of the Mun.
Kerbal Space Program is an indie sandbox game developed by Squad http://kerbalspaceprogram.com
