Indeed, except...Those are Themepark, not Sandbox.
Sandbox is what ESO should have been.
Themepark is like a joyride minus the joy, a rollercoaster on a set track, while a sandbox is well..A sandbox. You can build castles, make landscapes and so on.
The metaphors should make it pretty clear which one fits TES best.
The Rollercoaster can be fun a few times, but it makes you sick soon if you keep using it.
The Sandbox never stops being fun.
