No question about it, it'd be the gorgeous Redcliffs from AweSims. I absolutely love this world, it's just so bright and cheery! There's beachy areas, there's farming areas, suburbs, whatever you could ask for. Did I mention how cute the downtown area is? Because it is! And it's updated for Late Night, which can be hard to find with custom worlds. I think it's pretty much perfect. ♥
Yes, that is Glory Crescendo playing guitar on her lawn while wearing her nightgown. What of it?
