I can give so many but you’ll have to narrow down your preferences a bit ^^
I’ve recently been playing Remnant 2, Songs of Syx, Age of Darkness, dotAGE, Helldivers, Valheim, Against the Storm… all really impressive and amazing games made by (relatively) small studios or AA developers with a passion for games. If you’re completely new to the indie scene you probably can’t go wrong with Hades, Hollow Knight, Stardew Valley, Terraria
I really like this game! Wish it had more pve content, as it seems it’s very dependant on pvp interactions to spice up the late game, but even without that the exploration, combat and gear progression is really fun and engaging. The game also looks great and feels really good to play, neat UI and controls for both combat and building.
Basically, if it were primarily a pve sandbox game with AI to fight it’d be my dream game!
