I can only comment on Song in the Smoke, but it really depends on how you play it. If you look up how to do and find everything online it should be a 9-10 hour ordeal, assuming you skip collectables and go straight to the ending.
If you play it blind then you'll probably get 20-30 hours especially on harder difficulties. 

Keep in mind it's a single player game and once you've seen everything that's about it. I would definitely recommend it if you're into survival games. The crafting system is pretty fucking good.
