For events that are longer than 2 weeks, please ensure that a unique cosmetic is given to everyone that participates beyond a certain threshold.
For example, I hope that everyone that made at least 2 diamonds in the OtherSpeck challenge will get something unique and long lasting. I would love to win a random OtherSpeck mine cosmetic to place on my land. Or something like that. It would be incredibly disappointing to only win some sort of consumable resource.
