Hey! It's Ryan, the CreativeNation server owner! :) The idea that SexyToad had was to have the Giant Bomb Community Builders Club have a nice,friendly environment to build big or small community projects. The Black Mesa idea sound awesome, and would love to host a project like that. We will have sectioned off areas only for bombers, or even whole worlds for projects/builds. I am willing to provide whatever resources you need, of that means, WorldEdit,VoxelSniper,etc. Of course all build will be protected by anti-griefing measures, such as WorldGaurd. If you are interested, post in this topic, and SexyToad will keep you up to date with the release date of the server.
