@PhilHibbs I don't think FromSoftware minds the hate from Game of Thrones fans. 😝
According to posts in this site, RuneQuest is a better system than DnD 5e and Glorantha has a much richer and more coherent world than the Forgotten Realms. Assuming players of tabletop RPGs prefer better systems and settings in theory a little promotion should do wonders for sales.
I made the suggestion about George R.R. Martin because it seems RuneQuest or Glorantha has very limited online exposure. It's mostly word of mouth. If you look for "RuneQuest" or "Glorantha" on YouTube the number of views for most videos is really low.
There's this 2012 Japanese cartoon called Nyaruko: Crawling With Love! that blatantly promoted the Call of Cthulhu game (CoC). It supercharged CoC's sales in Japan. I am wondering why Chaosium isn't doing similar initiatives for RuneQuest.
On the other hand RuneQuest has been thriving for almost 50 years. The Glorantha-setting game Six Ages is on track for a sequel. So I suppose more promotions for RuneQuest or Glorantha isn't really necessary.
