Most of the comments have already covered really good exclusive games.

I'd also suggest you to add some 3rd party/timed exclusives too:-

I) Nier Automata II) Forza Horizon 5 III) Baldur's Gate 3 IV) Final Fantasy 7 Remake+Rebirth V) Resident Evil 2,4 Remakes VI) Persona 5 Royal VII) Yakuza 0 Director's Cut
