Its simplicity makes it appropriate for everyone to approach, and its difficulty levels provide adequate challenge. Plus it really makes you sweat and is a good workout, just make sure you don't sweat-damage your Vive, because HTC tries hard to wiggle themselves out of repairing those :D

Even my non-gamer wife loves playing Beat Saber. It's an addictive game, and there already are thousands of custom songs for it, as well as saber mods which allow you for example to play darth maul style, or using katanas. The possibilities are countless.

highly recommended!
