Could this walktrough behaviour be created with logic bricks? Click drag = tuns the view Single click = Moves the camera to pre-defined positions.
Camera animates to next position…
There´s also a map with hotspots for clicking and flying to. I imagine one would need to do a layered scene for this menu.
This was published as Shockwave 3D (needs free plugin to play). Could have been done in Macromedia Director´s 3D lingo or Maya RTA (Real Time Author, a discontinued Alias plug-in for Maya 4.0 only).
but anyways, to switch cameras (cycle through cameras?) you need to be able to tell where you are, python will be helpful there (especially when you want to add new cameras, or change the order, you wouldn’t need to mess individual cameras)
but for clickable areas that set the camera, you can model them and give them collision faces, use an on mouse over and mouse left button sensor, pulses on, connected to an and controller to do that.
To rotate the view, is the easy part. Already got that from the walkthrough example file at blender.org. My doubt would be how to set the invisible hot spots (with tool tips and one hot spot not messing with others) and the flying camera transitions.
