So basically, you're wanting to talk about things like accessibility/functionality rather than engagement? As a general rule of thumb, the less clicks and less searching required to do a thing, the more accessible the design. Trick is to maximize/balance functionality with accessibility. too complex and you lose accessibility, too simple and you lose functionality. Xbox 1 OS is a good example of getting nearly everything wrong, while ps4/switch OS do it better.
Kind of lost me on the item thing as well, though I've never played the game. Images comparing a "standard" and a "better" idea would go a long way. Though as a text-based forum, probably not the best medium to do it. I'm all for the idea though, just got to figure out how to design it.
