NekoCat from ModTheSims has a scenic world up for grabs. It is a pretty big world that is very detailed including lots, so it might take the higher specs, or deleting some of the lots to play as NekoCat mentions.
Make sure to stop by Around The Sims 3 to grab a uber cool gardening set for your simmehs. Looks like about 24 objects included in this set:
wheel barrels (One for the lil' simmehs and one for the big simmehs)
Seedling plants (I think decorative)
Fuzzy Logic Dishwasher has taken the warehouse from Riverview and converted it to a furniture store. The purpose is mainly for movie/story making. Your sims can visit but they can't actually walk up to a cash register and pull out their pixelated credit card lol. Nonetheless they can go fiddle round on the lot.
#406Renault Eco Friendly car - Official Download Set
The much anticipated Renault car and the recharging station thingy are now here. Looks like several goodies with this set! Make sure to change the language on the home page of Sims3.com to English > UK to be able to download.
If you don't see the link from here, just go to the home page of Sims3.com first to change language, then try again. =)
Even your simmehs that don't like the outdoors might be more inclined to go outside with this uber cool set of recolorable pretties over at Vita Sims. Looks like about 16 items included. Several lounge chairs/couches, decor, table and more. Had to grab this one for my simmehs!
Custom Sims 3 has lots of goodies to grab! Including wall shelves by Jynx that are stackable along with floor shelves that are stackable with quite a few slots. You can also find several cool worlds there including Broken Heart Island by Rflong7. I am linking you to the update page so you can see all the goodies.
With this mod by HugeLunatic from ModTheSims, you can now haz off the grid rugs, rugs at a diagonal, and rugs that don't sink into the ground! Very cool especially with the stepping stones rug from Family Fun Stuff. They can now stand up out of the ground the way they are supposed to.
Mustluvcatz from ModTheSims has some cool (or hot) chimneys up for grabs. These are decorative and come in 12 colors. There are three stackable pieces to this set so you easily use them with different levels up to three stories.
