>But I haven't played a really compelling game

I've liked a lot of VR games, but Out of Ammo was the first that really hooked me. The "sandbox" style -- not sandbox in the sense of Minecraft, but in the sense I felt like a kid again in my sandbox placing little army soldier toys around me and making little barricades and walls defending from imaginary threats -- was great. It's a shame that the game is a bit short and buggy right now. I think that style of gameplay is somewhere the Vive (VR+motion controllers) really shines and has a lot of untapped potential.
