I don't think you'd have to make it as full size as actual AC. About 50 items will do. You could even increase the variety by simply replacing the texture like posters or carpets or wallpaper.

OR if you really wanted to you could make the game 2D. The real focus should be on characters. Really nice character portraits and interactions. The world doesn't need to be randomized either. Just the premise of human moving into a small town with animal residents.
