Yes, it’s just the effects which are CGI and lights. On the original series they had smoke bombs.They're still physical aren't they? They still had to roll up and onto the little indentation
I don’t think it’s true they had to stop the sphere on the pod last time as noted above, you just had to roll over the middle and it looked the same this time.
In any case the spheres looked hardcore. The main difference I can see to the original is they seem to have put something down on the floor so the spheres slide about a lot more and have less traction. It seems to have slowed them down a bit but made them harder to control. The scoring pods are a bit shallower to compensate for the lower speed/grip.
