Home Design 3D isn't like the sims series where you design houses under a lot of restrictions. It's a game more focused on the construction and design of houses in real life. The fun factor relies on the construction of houses themselves. While there are npcs, they're mostly just for show. Don't expect them to be like sims! I would call Home Design 3d more of a program than a game as a result. I did experience several problems when playing, I couldn't make objects taller correctly; it makes everything wider instead. The program doesn't do much in the way of a tutorial and I found it to be very irking. I would recommend Home Design 3d to people who enjoy the home construction from the sims series but not the sim interaction.
