I'd get rid of the mechanic of getting unnecessary doubles. Specifically with randomized drops/rewards. I play Animal Crossing as a part of my daily ritual sometimes. I'd check for new recipes, get duplicates, and stop playing for the day. It's just not fun to reduce a game to work like that.
I don't think that there shouldn't be any chance or grind involved, but I think an invisible coding quirk that makes a new or desired item inevitably drop would go to reduce some stress.
I think sometimes grinds like that can really mess up people who can just dive into games or have that compulsive desire to get 100% completion.
FF7 doesn't need to be remade, it was part of an evolution of mechanics. Remaking it with modern stuff is pointless, it doesn't further the medium. And the story is too radically different for it to really be sharing the original with new fans.
