Freeform building and exploring, crafting, survival, pixel art, endless gameplay. There and definitely a lot of similarities, especially compared to say CS:GO.
Oh, and don't forget the insane modding communities.
Eh, i wouldn't call that freeform building and exploring. Rather unconstrained base building, sure, and open world exploration, but you can't disassemble the boss dungeon and rebuild it as a boat in hell. You can't automatically kill enemies in a pit of lava. There's no getting lost in your own mess of tunnels. And no one is making a working GPU out of Pals.
