Project Zomboid - harsh learning curve but fun survival
Avorion - Space combat and trading sim with block-building for custom ships.
Dwarf Fortress - very hard learning curve but you can sink thousands of hours into it and it will still surprise you.
Valheim - easy to start but difficulty scales fast as you explore
Or if you don’t mind proton some great survival/builders are:
Raft
Abiotic Factor
Satisfactory








What that needs is a smoke animation that starts as soon as your core temps get too high.
