If you want some 2D fights with crafting, boss progression and impressive mods, can't suggest this game hard enough.
Procedurally generated adventure game focuses on fights, crafting and mining. Multiple difficulties, with hidden world seeds for extra challenge, tight controls, and tons and tons of content.
The game is quite old, almost 15 years. You might have even already played it before. But if it was long ago - surprise, there's even more content now! Even graphics have improved, and the mods are better than ever.
The base game isn't too long, and I've always felt that it stops right after you start to get into it. Well, fear not, for there are mods that extend the gameplay off the cliff and into the sun.
Mods are installed and played with the TModLoader. If you buy it on Steam, you can one-click install mods from the Workshop. But they don't work when you open Terraria, you have to start the TModLoader.
The most important mod I've played the most is Calamity. Almost tripples the base game content. Definitely don't try before playing through vanilla, as it will feel very overwhelming. But after you know your way around the world, this mod will give you weapons that tear vanilla bosses like wet napkin. And bosses that will give you grief anyway.
Terraria is and always was just $10, right now at 50% discount on Steam. Very low specs required, and I've played almost 500 hours. And I will play through it again.
You are talking about freedom and peace, but only for the global north.
It wasn't like that for rest of the world.
