No doubt they'll have a wonderfully vague explanation for why the trees have stopped moving, and turn that into a quest line. Maybe you'll be treated to a one-time cinematic at the end of it of a walking tree.
Harumph.
Well, there are technical limitations to deal with I suppose.
Maybe not literally
walking city-trees, but certainly ones that change position so that one month it is located
here and on the first of the month it moves to
there on its cyclical migratory path.
If they are truly and completely stationary I shall cry havoc and let slip the dogs of war!
Ahem.
Be quite dissapointed.
