https://howlongtobeat.com/game.php?id=6591Nier, 21:00 (admittedly this is likely unrepresentative as Nier 1 should be played with endings B, C and D included, but that still puts it at 36:20 but conversely those routes are only actually a couple hours of new content in practice)
https://howlongtobeat.com/game.php?id=38029Nier Automata, 20:48 (again, same as above, 38:21, though more of this is unique content than Nier 1)
20 to 40 hours is an extremely normal time for JRPGs and it's where Pokemon consistently sits too. Search Pokemon on this site and see for yourself.
