This one was so nearly the one I used as my basis for Stardew Valley because of the big river running down the middle, but I wound up thinking it was too big to work for my purposes, regardless it's a really beautiful world with a lot of nice set dressing and is worth looking at if you're wanting something similar!

The colour palette for this world is gorgeous! It's so lush and full of greenery and I also really like the road design - if I was gonna build a town in this world I'd probably use the big spring / waterfall in the middle as a big lore plot point (eg: maybe it has magical or special scientific use & its use employs a lot of the townsfolk?) so many opportunities for storytelling here!

This one is a bit on the smaller side, but you have lots of room to place more lots if you do need more space - the scenery is lovely as well - there's a clear area for the town centre & city hall which is something I always like in empty world because it gives you some guidelines to go off of rather than starting totally from scratch planning-wise

This one is a super nice standard residential world, it would be great for a costal / fishing town vibe because there is a lot of big lakes and abandoned boats scattered around, I also really like the road style in this world (something I'm pretty sure no one cares about other than me LOL they're just very aesthetically pleasing & look super clean)

This one is one of my favourites for scenery but I haven't found quite the right use for it for my personal saves yet - it reminds me of a remote scottish island, and you get the impression there's a lot of lore here you can play with, there are a few pre-built community lots but they're mostly just for decoration and you can just delete them if you'd rather start from total scratch!

This one has a really nice desert vibe if you're looking for something less green! (the other ones on this list are all quite similar so I wanted to give another more unique option)

This one is small as well but it has quite a few lots packed into the space which is why I thought I'd give it a mention! Would be great for a small-town suburban kinda vibe if that's what you're going for, it kinda reminds me of Sunset Valley

This world is massive if that's what you're looking for! It's got an area for farmland and adjoins to a more industrial city part as well, a really great all-rounder if you're looking for a big project, I also love that it's got so much attention to detail with the different road types in the more rural areas and barns / hay bales scattered around the farming bits

This is the world I used for my SDV project so I'm sure you've checked it out already, but I have to give it a mention because the scenery & set dressing is some of the best I've ever seen, it's stunning, and I'm constantly discovering new details & little things for my sims to explore even after working in it for months
