Sylvanian Families/Calico Critters are so sweet. I never got into collecting them myself but I love seeing photos.
This person on flickr, Sylvanko, does the most adorable scenes

Forest Families are awesome, we had Forest Families and Sylvanians here in the UK so my childhood collection had a bit of both. I wasn't around in the 80s but Forest Families used to pop up in charity shops when I was little.
Here's some stuff I found when looking up about my Forest Families:
