If anyone is not bothered by these options not being in the game then I understand and won't hold against them any hard feelings for not caring as much about it as I do or others do.
I often speak about cookie cutter Sims, you know, family, 2.5 kids and a dog or cat etc. with a white picket fence. I have played that way too, but sometimes (more often than not) I have to try building something that isn't part of the scenery or wouldn't fit in with the current worlds. Things like the Colosseum, or let's take my DS obsession with that Collinwood house I built. I can't tell you how many times I have built that house in all the games, and in TS4 it was impossible for me to build it correctly to have the landing visible (inside) with the stairs not very tall. All most sort of like split level but not exactly. With terraforming this would have been possible and I wouldn't have to resort to a sunken drawing room etc. Because I'm a stickler for stuff like that. The house doesn't have a sunken drawing room in the old show.
That stuff matters to me. True the house was never used for the TV show, only the outside a stage in a studio in New York, lol, but if I built the entrance as it looks on the old show I would have to sink the drawing room to be able to show the landing leading from the staircase. Which would not be a true replica. That means I would have to add step down stairs, too, to the living/drawing room. That annoyed me so much when I had to add a foundation (which it doesn't have on the old show) so I could sink the rooms by deleting the floors. That sort of stuff insults my sense of virtual truth. That is just a tiny example of things I can't build in this game and represent a true replica.
You never know what inspires a person and when we run into a brick wall some of us are so particular with detail that stairs going down into the drawing room would make us just give up and say forget about it. And something I know I won't be able to build is something like the Hanging Gardens...I hope developers think about how imagination is stumped when we can't build what is in our mind's eye. It's all very unfortunate for some of us. ETA: And as far as someone else downloading something that I have built, I have never built to please other people, I build my imagination and or other blue prints, and it's for me, and has always been for me. ETA: Terraforming is one reason I could build things like Gondor or The Keep etc. in older games. Don't keep squashing possibilities, because a lot of us don't play cookie cutter Sims.
@Hermitgirl, I would not be able to build where I live now, because my land and house is not flat. My land has several landings and not just rolling hills. Some of my house is back underground which is part of the basement. Details matter. :) ETA: And I might as well forget about building an old run down castle high on a cliff overlooking the town below. That winding path leading up to the gate is not going to happen. :/
