Name another one? Where people could converge for food, shopping, and entertainment? The Greeks called it an Agora. Start there and move forward a couple thousand years, you'll find one or two establishments along the lines of what DTD is hoping to accomplish. Nothing new, and certainly nothing exciting. Then again, the Greeks probably didn't have seed and mulch. Columns perhaps, but not seed and mulch (unless the former was for planting)....
And it appears that what we know about HW is nothing more than wrecking balls, artist's renditions and rumors. Again, not much different than your usual suburban outdoor shopping project.
Disney formally announced Hyperion Wharf. Far more than a "rumor". Much more formal than FC. FC was always dependent on outside interests. HW not so much. Comparing the two is a trick and those trying it are rather transparent.
Again, name a place that has a mix like DTD does in one place anywhere else. The reason you didn't is you can't.
From its own Cirque show to all the Disney offerings to DQ to HoB to T-Rex to the balloon and on and on. The are not all unique offerings necessarily but having them all in one location in such a beautiful setting is unique. And they still are probably only half finished.
PS Before you lump me in with the crowd that wants the AC gone, I have always thought it and the Comedy Warehouse should stay and are perfect for the area. And I have said so several times.
