I'm from Europe and it's especially bad in that sense cause for example HP and Lenovo has a generic budget headset with controllers for $150 but that's US only. You won't find anything that close in price here
The controllers worry me the most since I don't know if they're required or if they need certain buttons I can map things to.
So yeah, right there with you. I hope it's worth trying to buy it all, but it's a big hurdle in a lot of ways so the game has to be amazing.
Lastly, since my life has changed a lot in the last twelve years, I no longer even have a real gaming PC (I assume I'm not the only one who lost that as they aged). So that's one more cost I have to factor unless maybe they release it on PS and I can buy that and it's VR rigging.
That said, we don't actually know the requirements yet - as far as we know it'll require full finger tracking or be straight up Index-only (as unlikely as I personally think that is, it's still possible). Definitely don't pull the trigger on anything until the full announcement on Thursday.
