You can totally do it. Every food is technically a luxury but the mountains has everything you would need to hold a piece of wolf meat over a fire. That would be where the challenge and the roleplay of such a ruleset meets in the middle. No microwave meals or takeaways for you.

That's actually one thing I don't like. The mountain is such a cool biome but there is very little reason to build a base there. OTOH I'm not a big fan of the flax/barley restriction to force people to settle in the plains. Feels forced.

Agreed. But the restriction doesn't feel as forced as it does pointless. The farm yields have no teleport restriction and even if many of us prefer to ban ourselves from world-hopping, it's in the game by design. The farming restriction makes things neither more difficult or more easy. The very fact that the restriction is so logistically inconsequential is what makes it feel like a nuisance.
