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.
d10 systems are clearly the best for TTRPGs. The d20 creates too much variance and the mix of flat bonuses and dice bonuses, (+1 weapons and advantage/disadvantage) feels awkward.
Women and minorities aren't historically accurate. Hella bothers me that something can be flush with fantasy but then the gamers pearl clutch over ancestry and traditions and nonsense.
