I have greatly enjoyed the "show me your Oasis Springs" thread and get so much inspiration from seeing all your versions of the worlds. So I figure it's time for another: Show me what you've done ...
I have to agree with @DaniRose2143 that your Willow Creek makes mine feel so very basic, @musteni. :lol: I honestly put very little effort into Willow Creek in my current save game. Perhaps because I'd just gotten bored with the world as a whole with it being one of the only worlds we had for a while when the game first came out. I dunno.
Anyway....Mine is still mostly all just residential. All of the homes have been renovated, but nothing special to mention. https://64.media.tumblr.com/9c4047d800e929915f1c5d183294584e/195df674a16dfc2b-0c/s2048x3072/6b092a419ad608d2a40e7404a25f25360915da07.jpg
Magnolia Park got the standard park treatment in my game, which just means it's got a lot more 'stuff to do' than it originally did. It's not one I visit all that often though.
Crawdad Corner kept it's place as the only neighborhood in the world with community lots. All of the originals were replaced/renovated, but that's about it. It still holds a Library, Gym and Nightclub, just like it originally did. The museum, however, was replaced by a Cafe with a small playground and wedding arch beside it.
Sage Estates is still upscale homes, with one family of note long in residence there. One branch of the Tinker family has made their home at Oakenstead.
Courtyard Lane got a Tiny home at Rindle Rose and then just standard renovations at the other residential locations. The tiny home is residence to one of my played sims, and other families of note are one branch of the Beaker clan, who live at Brook Bungalow and some offspring of the Cavazos and Watson families who live at Riverside Roost and Pique Hearth, respectively.
And Foundry Cove, where the Broke family has set up residence at Daisy Hovel and the descendants of Laurent Dupree (who are also descendents of Victor and Lily Feng) live at a not-so-bargain-anymore Bargain Bend.
