Would you want to come onto one of the servers and brainstorm with me?
Might be possible, but i am kindof tied up right now in making a town in creative for a showcase, and it may take significant amount of time. I would sudgest that you choose first what is going to be targeted population, for example PvP-ers, or casual builders, casual roleplayers with affinity to make politicly incorect jokes etc. You cant please everyones taste, so first make a choice what you would preffer to have.
Easiest would be to have UHC rounds for people to record their gameplay, you can also make a premium service with 1$ participation for event of UHC with random loot drops etc ....
My personal favourite would be comunity build projects, like making a town in themed style, examples Wild West, or Sci-fi ruins, Dwarwen mines etc. But dont take my guidelines, theres a lot of people here with ideas, and on the end you are the one to choose.
