There was a friendly competition here where the members of this board did a weekly challenge and then post how they do here. The challenge could be "get a new high score in challenge mode" or "get 100% completion of an area with minimum casualties", and the winner would be whoever got the highest score, or the fewest pikmin deaths, and they would pick the next challenge.
Kind of like a riddle topic. But instead of who answers correctly first makes a new riddle, its whoever does the best makes the new challenge.
Would anybody want to do this?
