my choice would have to be stardew valley..what games do you recommend?

Abzu, despite not liking Journey at all. It was gorgeous and serene with one heck of a soundtrack.

INSIDE is short but sweet.

Brut@l is totally up there.

Another vote for Abzu, and Inside, and let me throw in Enter the Gungeon and Downwell (which was 2016 on PS4.)

It also depends a little bit what you mean by Indie. I might throw in Firewatch but that's kind of a "big indie" with production values and promotion.

Hyper Light Drifter, probably

My top 10 games last year included The Witness, Inside, Firewatch, Enter the Gungeon, Hyper Light Drifter, and Salt & Sanctuary. And though I didn't play some of those on PS4, all are available there and were released for the platform in 2016.

Furi.

Salt and Sanctuary.

Oxenfree.

I honestly really liked Amplitude. The soundtrack is very weird and niche but I like it. Also all the bonus unlockable tracks of songs from other indie games are really cool too. The game also has a pretty great look and feel.

I also really like Hyper Light Drifter, am working my way through Salt and Sanctuary and digging it, and Inside is okay.

On a side note this might be the year that I may have sadly sort of fell out of love with puzzle-solving games. Used to be, and kind of still is, my favorite genre but with this year I felt like Goldilocks "The Witness was too difficult, Inside too easy" I had a hard time finding a good puzzle game that fit me just right this year.

Second side note: Thumper is good too, although I think Amplitude is the more fun overall of this years rhythm games.

Inside and The Witness are masterpieces.

I'd say Firewatch but the last third of the game is so disappointing

I like Inversus. A nice, neat take on the arcade shooter.
