would people like to see hardcoe mode come back and what would the like it to do

Like I said in the other thread, yes!

I'd like to see the mechanics of hardcoe mode incorporated into normal gameplay, so that they don't feel so detached from everything else. Stimpaks should heal over time and be considerably more rare; food and drink can be made useful (without arbitrary hunger/thirst bars) by enabling health regen. Sleep could govern AP regen, or even XP gain. And ammo having weight regardless of difficulty is fine; maybe just include a hard-to-get perk that makes it weightless for the convenience factor.
