Just had to refresh my memory via Google; in their first year, in terms of AAA "next gen" exclusives, PS4 and Xbone got:
- Infamous Second Son
- Driveclub
- Killzone Shadowfall
- Sunset Overdrive
- Dead Rising 3
- Ryse Son of Rome
- Lords of the Fallen
Most big games were still crossgen even back then, but unless there are multiple big PS5/XS exclusives coming this year we don't know about, it's still better than the 9th gen's first year is shaping up to be.
