Which indies did you discover and would love more people to know about? I’ll start: The Pale Beyond. Not sure if it’s a hidden gem tbh, but it’s such a good story rich game. I laughed, I cried and felt the characters struggles. If you like story rich games/ choices matter, check it out.
They are hidden, so I don’t know about them. Sorry I couldn’t be of more help.
The Witcher 3 (/s)
Citizen Sleeper - From the same publisher as The Pale Beyond, it’s another one of those story games that borders on visual novels. It’s a game about precarity and personhood set on an anarchic, decaying space station. Gorgeous art, fantastic soundtrack and it’s uniquely hopeful. Might be favourite game of the last few years.
Parkitect - an amazing RCT spiritual successor with cute graphics, some new mechanics (covering operational buildings and logistic routes). I have 100+ hours in it with my wife. It’s such a chill experience.
Nine Parchments - its a dual stick isometric shooter with wizards and elemental spells from the creators of Trine. Great co-op, unlockable characters/spells and creative mechanics. You can combine elements and the spells affect everyone, so for example a poorly placed healing spell can restore enemies health, or a misplaced fireball can hurt fellow players. Great fun!
Wildermyth - turn-based rpg with multiple characters and bite-sized modular quests and random encounters. The storytelling is simply amazing and each campaign plays out over a certain amount of time. The heroes age, retire, their kids can become adventurers as well. They can fall in love, compete, or based on the player’s choices even become other creatures or die heroic deaths which will also change how the story plays out. The art style is really nice and unique. I had many hours of fun with this one.
