The item limit is punishing and I would definitely love to see an increase but I actually enjoy the push for creativity in it. If your house is "empty" than you need to fundamentally rethink your design to make use of the space and the item limit in a more pleasant way. The other option is to cut off space and a lot of people prefer to design smaller but for me personally it's fun to try and maximize the spaces I'm given to tell a more immersive story. The struggle is what makes it worthwhile to accomplish a really cool build and I enjoy that sense of satisfaction afterwards. I've been lucky enough to have a chance to decorate every size of home available and the challenge of a full floor plan is always exciting.
