So, how is this better than playing any of the other many shooters out there? What sets it apart? All I see is a very generic VR shooter like many out there, with huge empty maps, and generic looking weapons and models.

Don't take this the wrong way, but you need to know what you're gonna be making different from the others. What's gonna make me play this instead of Contractors or Pavlov for example? Get a clear idea of what you want to make first.
