Build
What can you build in ScribbleBuild?
Whatever you can draw the pieces for. In ScribbleBuild the players build everything, so the answer depends on you and the friends you are building with.

Nothing is there until somebody makes it
ScribbleBuild does not hand you a finished world. The players build everything. Every tower, vehicle and bridge in the world exists because somebody drew the pieces and somebody put them together.
So the game is as big as the people playing it. A small idea gets you a small build. A big idea gets you a reason to call your friends.

The pieces come from your drawings, so no two builds use the same parts.
Open space
