User blog:ImARandonGamer/Community idea where everyone contributes?

Hello people. I'm wanting to try this and see how it goes. What if everyone started coming up with an idea together? Like a boss or an event or biome or something. It won't just be one person doing this, it would be everyone wanting to participate. I don't have any clue where to start, but other people might. Share you ideas, and let's see where this goes.
