They could do that, yes. But how long would that take?
There’s a concept in software development that goes something like this: “release early, release often”. That that means is: release a product that’s good enough to enter the market, but keep on updating it and improving it often, as users try it, break it and provide feedback.
That’s a great way to have something out there that is being shaped by the audience and not just by the developers and producers.
I believe that’s what Microsoft did here.
Granted, they could have added VR from the start (they admitted it was a mistake not to do it in the first place) but helicopters are something that would be a bit more tricky as they depend on the base sim, base physics and base flight dynamics to be top notch.
Based on the “release early, release often” strategy, I must say that I am willing to wait. Money would not solve the problem here. But precious feedback from the thousands of simmers that are using it, is a huge help.
