"Aimlabs VR" is a VR exclusive version of Aimlabs, itself the most popular FPS training software around... basically for people who don't enjoy playing video games but want to be good at them. Weird market. Anyway yeah, if you wanted to be good at video games and you liked playing them, you'd just play them to "get good"

While Aimlabs is very popular, this VR version is a complete flop, it crashes for most users and isn't compatible with most VR headsets... and VR FPS games are a tiny subsection of a tiny subsection of the Steam store. This really is an application for nobody.
