I'm a huge fan of re-ment! I don't buy them anymore because I have nowhere to put/display them, but back in high school my friend and I invested a huge amount of money into them. I was really into blythe dolls and other dolls back then so we'd always take photoshoots with them posing with re-ment sets. I dedicated a whole shelf on my bookshelf for it because I didn't have an actual doll house :'D Fun times.
My favourite was the re-ment mushroom series.
