Despite high memory prices, 007 First Light system requirements recommend 32GB RAM for 1080p

Recommended settings are for the average user to plug it in and get that performance. Have windows doing stuff in the background, a couple chrome tabs open and you need more than 16GB. 18-30GB are not valid ram configs on intel desktop or AM4/5 so 32GB is the closest.
