Alan Wake got "decent legs" by releasing on the PC through all the various digital retail outlets. Quantum Break is a Windows Store exclusive and uses the near-universally panned UWP format. Quantum Break simply will not have the legs that Alan Wake did, at least not on the PC.
I know, it's more me just wishful thinking more than expecting, just hope Remedy can survive it. I'd imagine MS took the fast majority of the hit, but having big expensive bombs is never a good thing, especially not for an independent studio.
