How much do VR games cost?

So, I'm curious, just how much do VR games typically cost these days? I've been hearing a lot about the immersive experience that VR gaming offers, but I'm not sure if it's going to break the bank. Are there different price points for different types of VR games, or is there a standard cost that most games fall into? And also, are there any VR games that are free to play, or are they all paid? I'd love to hear your thoughts on this!
