Grinding? There's little grinding.
Perhaps you should look into optimizing your travel routes and shipping mechanics.

Unless you consider mining for copper once or twice in your life "grinding", then well.. This game just isn't for you.

If you're not into building a base, collecting resources and what-not, then don't do that. Focus on completing the game instead.

There are mods and cheats if you don't want to haul your stuff back to base.
But imo, you can just spend 5 mins on a boat getting it back to base as well. Or enjoying the physics of going downhill with a fully loaded cart.
