My problem is the size. Sure, big is good, but I don't want something that nearly caps the brick limit again. I can't make anything with that. You release that, like your cities, people can't make anything decent without destroying half the build first and then it just looks weird.
The build has more 'replayability' if it stays small, but big enough to satisfy.
That and all of the countertops in the rooms were up to eye-level on blockheads.
