You might. Flight sims are one of the most immediately compelling things to do in VR, and a controller is a huge step up from nothing.
I have yet to find a reason to buy and keep a VR headset as most things just feel so gimmicky to me. At this point unless you’re either tethered to a more powerful device to be able to do the heavy lifting for the headset or you have a standalone headset that can play some basic arcade like games. A single device that can be taken on the go and play new releases not made specifically for the headset would be amazing to me. Obviously until it’s released who can say what it will actually be capable of but if it has the equivalent power of a MacBook, when my mid 2015 MacBook Pro finally dies I’d honestly consider replacing it with the vision pro but wouldn’t run out to buy one to have in addition to the MacBook.
