There is a version of Calm Down, Stalin - VR that doesn't require any VR hardware now and it's called Calm Down, Stalin - The First Person. And the best thing - if you already own Calm Down, Stalin - VR, you get it for free! Just launch the game and you should see a new launch option now!
Please note, that it's not supposed to be a new game or remake, it's just an attempt to adapt existing gameplay to mouse and keyboard controls without the VR headset. As such, gameplay could be not optimal, but hopefully still fun!
Calm Down, Stalin - The First Person - no VR required!
