Like others have mentioned, I joined Carl's Sim's site to comment on this new version of Sunset Valley. The world of Sunset Valley, in my view, was always a 'starter world' that becomes boring as you add other expansion packs and more interesting, vibrant communities. So to come upon this new version is like being swept out of Kansas into Oz.
However...
My initial game was far less than sub-par. In fact, I never got to game play as I entered EDIT TOWN for some basic tidying up. (eg. renaming some Subway stations, marking lots with the 'Bench' tag is Hidden Tombs, etc.) Twice in a row the game crashed on me. Now, to be clear, I did replace the original Sunset Valley World in the /non-packaged directory of the Origin game directory with EllaCharmed's fixed world (ie. the 85mb file.) So I can't imagine a conflict there. And yes, I realize Sims 3 is a buggy game.
I read above that others had much smoother game-play, so I am assuming there is something wrong on my end; something I might have overlooked.
It should be noted that upon loading the saved game file, the town screen filled up slowly (not very slowly, but slowly.) I actually watched all the lot tags being produced on the screen, which is not something I ordinarily see. I just assumed it was a big game world. But once I dropped down to my household and moved around a bit and in and out of town view, I was a tiny bit frustrated at the jarring lag. For the record, I do not have an old computer. It is a 2019 Alienware with 64GB RAM, a 2TB SSD, a high-end NVIDIA graphics card with 8GB dedicated memory, and a high-end processor. So I would say that is a bit over-kill for The Sims, but I got it partly with the intention of playing a smooth game of the Sims. If not too much trouble, I am hoping maybe you can give me a bit of direction of what I might be overlooking. I'd appreciate that.
And also, thank you for what does appear to be a beautifully re-imagined notion of Sunset Valley!
