One key feature in The Sims 4 is building. While the gameplay and character creation are important, many players only use The Sims to build houses, public lots, and communities using the extensive and complex Build/Buy mode. Simmers who use cheats or mods have even more control and freedom when creating the perfect lot for their Sims or to use as a model. However, some things are not as simple as they may seem for those who want to experiment with realism or creativity in their builds. For example, roof building stumps some players and can be an afterthought.
