Gaming-focused Apps
Software is versatile, and doesn’t have to simply cater to one demographic. That being said, there is oftentimes software that has a focus on a target demographic but can also cater to others not interested. Take software such as Discord: It’s a voice and video over IP application that focuses on gaming, but can still be used by others for non-gaming users. Gaming-focused software can set itself apart with high performance and a more “hardcore” aesthetic.
