Ds2 is the most rpg of the titles, making it the most replayable one, too.

Tbh until dlcs come along I have no interest in playing ER again after playing just once. It simply feels like no matter what weapon or magic choice I make, the gameplay will simply be too similar.

Bloodborne is perfect for one playthrough only. Subsequent playthroughs and the god awful chalice dungeons fall apart, partly due to the horrible progression and itemization in that game.

Only Sekiro is replayable despite barely being an rpg, because it has interesting different endings, and the bosses are the most solid in From's history.
