It’s effortless and no creative inspiration whatsoever. Only those who have the resources can win the competition.
Make it into art competition where the set with the most unique design, animations, and whatnot that fit the theme will be added and given only to the winner as an untradeable vanity set.
Or better yet…
1st Place: Wins their complete set as a vanity untradable
2nd Place: Only gets to choose 1 untradable piece of their desired set and a consolation prize of 50k gems.
3rd Place: Gets to choose 1 untradable piece from their set.
That’ll wipe out the randoms and nakeds who keep on joining.
Don’t they just have to copy paste the basic object data documentation and tweak it a little? Just the name, description, and object type. Then insert the provided sprite sheet and animations into the game and tada?
