PS5. XBox only really has one exclusive I still like from MS, Forza Horizon, and I can play that on my laptop. Plus PSVR 2.0!
If the new flight simulator runs like crap on my laptop and it's supposedly brilliant on series X, then I'll be interested. However it depends on whether my flight stick will work with the series X and if you can connect a keyboard and mouse for all the shortcuts and operating the nav systems, otherwise no point.
