I've seen some children move onto Unity for the 3D graphics. Physical computing can sometimes give an incentive for Python when its the only lanaguage available. We've done some stuff with Minecraft Pi at code clubs I've been involved with. although it's such an early version of Minecraft. My elder son likes maths, so we've done some mathematical things in Python, which are easier in that, although probably wouldn't be impossible in Scratch.

But it's tricky!
