I just had the great idea while running on spawn's walls. We should have races. Two people stand at one end and they stay on their own side (Split by the Glow Stone) and when they say go the run, and who ever wings gets a diamond. When they win they also, get to go against the next person and if the keep winning they get to keep racing every time and getting diamonds. No one is allowed to have fly on or any poisons. Who would do it with me? ^.^ And if you have any more idea what's to add to this. ^.^ This is going to be so much fun!!! ;D :D :)
The only issue with this is that you always run at the same speed, so you would always draw, or lose because of slower internet.
That's the point. If they have slow internet and may not know it they will lose.
