Yeah, all the sandboxes I mentioned above actually place some significant limitations on the players. In the West Marches campaign for example the PCs have to staty in the West Marches. They can't travel to a distant continent or all the GM's work will have been wasted.There is value in setting some parameters of character creation to get them pulling together so the group can have a game.
Likewise the classic D&D sandbox assumes the PCs all want gold and magic items and are prepared to risk terrible danger in order to get those things. In other words, they all have to be greedy psychopaths. If the PCs just want to open a pub then the game doesn't work. Likewise if some of the PCs are normal people with a normal person's attitude towards monster-filled holes in the ground (ie don't go anywhere near them) then classic D&D doesn't work. I've seen this happen in D&D on more than one occasion actually.
