I'm playing through Hollow Knight and I'm almost finished - but I still think Celeste is the best indie game all year, and it's still my favourite game I've played all year.
Beginning of the year Celeste was my indie goty but playing hollow knight was a revelations.....tried playing Celeste today and everything from jumps to wall climbing feels wrong now :/
Huh. Hadn't really considered Subnautica an indie 'cause the production values are so glorious. But upon reflection, I guess you're right that it's an indie.
In that case I change my vote to Subnautica or Football, Tactics & Glory.
This thread is great, its opening my eyes to some great indies! Recently bought into the breach, its great. Gonna pick up celeste, dead cells and hollow knight thanks to this thread!
Celeste, Iconoclasts, Unavowed, Heaven will be Mine and Subnautica have made this an amazing year for indie games, though I don't know that I'd pick any one of them over the others.
