Sad part is Epic don't really monitor this sub much now. I've lost a lot of heart in building on Creative since I can't publish. I've already made 2 great maps I've spent weeks on.
Not trying to sound rude to this creator but one map I've seen published was a map based of another game and it was lazily made of player structures. Even the rooms weren't exactly the best size.
We're working on better ways for creators to surface content. We do monitor the sub as much as we can and get a lot of featured content from here. It's definitely a priority for us.
