Don't really have one, they all had the same level of though poured into them. The main room is the cafe, with the room on the right the restroom, the back room is the outdoor backyard seating area, the left is the kitchen for the cafe, the upstairs is the 7-11, and the downstairs is the Nintendo museum.
I have a lot of towns, so my favorite rooms are....
Ms. Honey's queen bee room.
Witch Annie's monster party room.
Butterfly bedroom.
Rubber ducky bathroom.
Italian pizza parlor.
Superman bedroom.
Sunshine kitchen.
The elves workshop at the North pole.
And I really love all the rooms in my mayors house in my Cherish town. They are themed after special ac characters.
My house is still being expanded, but so far my favorite room is the kid's room (don't have pictures at the moment)
It's going to be a room that looks like 3 kids live in it. I have a bunk bed and a cradle and I plan to add stuff like a ballet outfit and a basketball outfit and other thigns to kind of show what these 'kids' are into. I'll also be makeing a kitchen and a homeschooling classroom, and the basemeant will be inspired by That 70's show, it will have a washing machine and such but also a tv and a couch and maybe a pinball machine, and then there will be my mayors room. No matter what room you go into, you'll be able to see that 'kids' live there. I've had this game for nearly 2 years and always wanted to make this kind of house, but never got around to it, I speant so much tbt to get what I need I can't wait for everything to be done!
Well currently, my favorite room is my main room filled with collectibles from other game series. But once I expand my house more, I will make sure my kitchen is done and then the bathroom. I also want to redesign my bedroom in Animal Crossing: New Leaf.
I like my music room that I have on top. It has just about every instrument that isn't DLC. I also like my Princess room that I mixed with customized Rococo furniture, so that it's blue and matches the Princess set.
I like the main room in my mayor's house which is the Mermaid set with items from the island. I just really like the sea globe. I also like the Princess themed bedroom. In my second characters house they have a dining room and kitchen that is just so cute. I made that house with rooms similar to real ones so I really like it.
