I’d like to add two more things:

It was the generation of HD remasters, so a lot of older (high quality) titles are available on the platform, such as the Dead Rising games, the Mega Man collections, almost all the Resident Evil titles, Devil May Cry collection, Bioshock collection, Final Fantasty X/X-2.

And most importantly, since they are last gen, they are not stupidly hard to find yet.
