One console, one game

If you could only re-experience from new one game (like total immersion, wide-eyed wonder-at-the-majesty-of-it-all re-experience) and had yet to pick a console (Xbox versus PlayStation), what game on which console and why? (and feel free to remark on ideal controllers, add-ons, etc.)

I was hoping Starfield might be that kind of galvanizing experience, but the reviews are pretty underwhelming. So now casting about for the real deal.
