The only point I’m missing is that of your needlessly aggressive tone. Regardless of whether or not the vendors deal only in gp, the price inflations on items are unnecessary. You seem to be conflating two separate points I made in this post.
Not conflating.
I was only addressing one of your incorrect statements, that the streamlining of the currency was somehow unique to Larian. That is factually incorrect.
Your assertion that the original BG didn't inflate prices is also incorrect. If you compare book prices from 2nd edition Ad&D to BG you will find that 's BG's prices are inflated for all items from what is in the source material.
You are attempting to throw shade at Larian based on two false premises.
If you consider it aggressive to point out that you are being factually inaccurate then that is on you.
