Like other people said, you can create any type of game you want.
You do have to keep in mind the fact that you will need a minimum amount of ratings and people have to play your game to rate it. Not everyone has the hardware to play a webcam or VR game. Heck, there will be a large amount of people that don't even own a controller to plug in to their pc and are only able to play with keyboard/mouse.
In short: Yes you can do VR but it's not smart if you want to win.
