Part Cost Value $$$...
Doesn't have to go beyond simply adding text to part descriptions and a "cost total" readout in VAB. Just having that would create a whole new gameplay loop of challenging yourself to find the most efficient builds cost-wise instead of simply weight wise. It would add a whole new suite of possible developer chalenges and influencer content as well!
I've never played KSP1, and am an avid fan of KSP2! I understand there was cost as part of a whole career mode in KSP1. I'm not talking about any of that! (Yet) just putting one of your developers behind a few hours of assigning a cost value to each part and the sum tool. Very little dev work = HUGE gameplay potential.
