Ooooooo this is all spectacular food for thought! (And actually has me really thinking about re-designing the visuals of a few a few things) - There's definitely some vestigial design after 3+ years of dev (a good example being how big the prices are even though that's all but standardized) and focuses in general kinda fell by the wayside in favor of just getting the game done ((and I still really need to do that 0.14 editing pass cause woof the typos)).
This honestly has me wanting to repurpose that "Cost" spot for the specific "Stat" focus of each part, then replace "Focus" with like "Utility" and pick like 9 keywords that there's a glossary for and each part would likely have 2 ((Though TBH I've been considering getting rid of the "Focus" spot altogether cause I question its ultimate utility vs listing the Element and Stats the part uses for quick ref)).
It can't be said enough how cool it is to see someone deep dive into this game like you are, and this feedback is the kind of sublime "fresh eyes" constructive criticism that I really treasure ((and seriously it's amazing you got through all 180 parts - Heck writing descriptions for all of those was a huge part of why I needed to take a looooong break after getting the beta out)). Honestly this is helping motivate me to keep plugging away at 0.14, so thank you fr.
