im a bit confused.............does only one person get to use a save file at a time for building. ive seen youtube videos with multiple people buidling stuff online and even chatting. wouldnt it be easier to do it that way for consistency and also so people dont have to wait for someone else to finish.
That would be multiplayer. It's very common and there's servers everywhere. BGSF has its own server, and many of the people here take part in other servers with their friends. And it's good, though it's got some bugs.
What we're talking about with the shared map is singleplayer only. I don't tend to do multiplayer, so this is sort of a 'lite' way for me to share creations with others. Like a puzzle that everyone puts together on their own time. Yes, you have to wait, but eventually it will look every bit as good as a multiplayer map (or better, because there's a more unified process) and without some of the bugs or other annoyances that can go with multiplayer, either.
