Much as you can watch a replay of other player's multiplayer games by browsing the leaderboards, I think being able to watch a replay of the results of other players' optimization submissions would be very educational. Wouldn't it be nice to see how the #1 coder landed the Mars Lander with so little fuel expenditure? Of course this is hampered a bit by the fact that the actual scored verifications aren't even visible to the submitter. Is this something we could see in the future please?
