World Suggestions

Great Bear: https://www.thesims3.com/assetDetail.html?assetId=5182185
Even though it's based on the northwestern states, It reminds me of the White Mountains in New Hampshire.

Salem, Mass: https://thesims3.com/assetDetail.html?assetId=7148668
This one is based on Salem, Mass where the salem witch trials were.

Amador: https://thesims3.com/assetDetail.html?assetId=4187730
Again could be used as a New Hampshire/Maine/Vermont world.

Cladbridge: https://www.thesims3.com/assetDetail.html?assetId=7451577
This one could be used as a small farming town from CT.(its based off of another country, but reminds me
of farming towns in New England)

Hmm maybe something like Brightpoint? I'll add to this if I find anything else, but I've played in Brightpoint and it's very quaint and it definitely reminds me of New England (though I'm from the opposite side of the country and have never been to NE :p ). It's very small, so whether that is a drawback or not depends on how you view it. Also, all houses come unfurnished. The rabbit holes are quite cute because they're in the basement, allowing the creator to make buildings that fit the aesthetic of the world. The same creator has more worlds if you end up liking Brightpoint.

Perhaps you have already looked here:

Port La Forks, WA and Hammond Island at MTS and Meadow Glen and Salmon Woods at MSR seemed close, but I've never been, in game nor irl.

Thank you for all the suggestions! I see some very nice worlds here!

What's a New England Feel? I've never been to New England.
And does it have any of the Showtime stuff or the Big rabbit holes or any apartments? Would it have to always have to be fall? Seems all the pictures I see are in the fall with a LOT of trees. :)

I've got one in progress based on Riverview only it won't be coming prepopulated or with lots placed since I would want to get it done ASAP since I'm also looking for something similar to the OP.I've got to get into CAW and finish working on my RIverview makeover since it might be the best option.I did also use Storybrook County lite and locate it in Maine for the 100 baby challenge I'm playing which is in the 16th century.
EVERMORE FALLS is another very highly recommended world where my Evermore Falls,Maine legach challenge in the 17th century is taking place.

Doesn't always have to be fall, just so happened to be fall in my game when I took the screenies lol.New England is small rural towns, farmlands, beach towns etc.If I were trying to find a new england world, I'd want showtime venues, but not like the huge ones, just small ones.And few small dive bars.etc.New England has a lot of old charm to it, Colonial homes, Victorian homes, farm homes.

To be honest I've been searching years for a world like this, the closest one I could find was Great Bear as it looked like New Hampshire.Someone was making a world called Coventry and it literally fit the description but they never finished it.

@Springfairy556 Oh, so doesn't have any of the big rabbit holes or builds, just mostly open tree areas with a certain house style which makes it the New England feel?
Iirc, that world used the fall trees and it was small but still very pretty.

@Rflong7
Well, not all towns are small.For example, Portland Maine would probably have the big rabbit holes.
But where I'm from was a small town of about 1000 residents.It had a school, a church, a museum, and a small gas station.
Was about an hour from the nearest grocery store lol.

Hartford CT would have a lot of big rabbit holes and night clubs and such.It all depends on what city/town you want it based off
of, for me, I'd be more inclined to a small town rather than a capital city.

Most of the time you see New England with fall pictures because its famous for the changing of the leaves.But they certainly have the 4 seasons.
New England is known for its backwoods, winding roads, country life.
