I wonder why it isn't more like an FPS. I understand there's more modelling work involved, but it would totally rock. Imagine if advanced engines like Unreal were put to work for this kind of things instead of just for games.
It can be bought independently on PC and is quite cheap[2] — it was being given away for free recently.
