Isometrics

An isometric world is the easiest type of 3D world to create in Flash because there is no perspective change. An isometric system is created by rotating a system that is currently aligned with the Flash system by 30º around the x-axis and then by 45º around the new y-axis. (iso ("the same") +  metric ("measurement") = isometric)

It's a familiar perspective, even for a "fly over" of a traditional game:

 Flash Examples
