I can, actually. Much less focus on movement generally (a few classes have a little more mobility, and depend on it). Closer to the classic Diablo 1/2 formula, with the addition of having the ability to mix classes a bit (think Titan Quest). VV was also more 'scenario' based on terms of how the world was laid out, you almost went on individual missions through a given map... GD is really just one gigantic map, with a few exceptions you can run the entire game from start to finish without hitting a loading screen. Dungeons, caves, and a few building interiors would be exceptions.
Also has far more customizations when it comes to class abilities, in multiple forms... Closer to Path of Exile there (though not quite as freeform).
Hope that helps.
