That's the most crucial point for me.
- I don't like this habit of splitting an already very small market.
- I don't want to have all the Oculus services on my computer. The store itself I don't mind.
- There is no guarantee that spending money in Oculus store on games played through Vive will mean the games will work tomorrow too.
Not just on Vive right now, but if I buy a Huawei Rive 4k HDR HMD in 2017 I'm pretty damn confident that I'll still be able to use it for all my SteamVR games. On the other hand, I have no confidence in anticipating what Oculus does tomorrow -- they already tried hardware DRM once.
