Actually, it did work. For Battletech, for Storyteller, and for 2e, 3.5, and for 4e -and for PF1. It's just that 2e and 4e had the minor problem of it not being nearly enough, because 2e couldn't, in spite of so many dedicated fans buying every book it spat out, generate enough income to offset losses on novels, and the failed collectible card & dice games (and general mismanagement), and because 4e was given a yearly revenue goal like, 5 or 10 times the revenue of the entire industry or something.
