What are the best Sandbox games on PC?

duplicate.

You can play on journey mode or on softcore to relieve the grind or you could cheat with mods, there is nothing stopping you if you want to beat the game

Peaceful mode is an option and no fighting is required, being a vegetarian inside the game is also possible and getting netherite without killing anything is also possible. The dragon doesn't have to be beaten and you could instead just build in the overworld or nether and never have to fight a creature. You could also go into creative to prevent having to fight as hostile mobs ignore you and you are invulnerable.
