It costs less than 200 bucks on ebay to find a Windows Mixed Reality solution. The "it's too expensive excuse" is nothing more than a veil of ignorance and stubbornness.
There are also other good VR games. Yes, some of us want to see VR grow, and this game condenses revolutionary aspects of what VR has to offer. Playing it in 2D is more pointless than just watching a playthrough. At least watching others play it properly, you can see how it was intended to play. I'd like to think that when people realize how bad it plays, they'll think "hm, well it's probably way better in VR so I can't fault it for sucking", but we all know it will end up being "this game sucks so VR sucks, next Half Life better not be VR and I'm gonna complain on the internet and send death threats to the dev until they give in".
I'm not mad, it's just stupid.
