I'm larging the groups and stating aspects of them.You are literally stereotyping groups by age. Older players are less diverse, younger players will get bored.
Generations Y and Z were not alive when OD&D was created. So no one under 40 affected the climate of the very climate of early D&D.Cause that with WOTC's graphs hat say more than 50% of 5e players are under 40.
And yes younger people tend to control the changing of popular fads and trends.
Only one of those is a completely new setting. And again that''s not what I meant by safe.As far as WOTC taking risks, not sure what you would have them do. If they had played it safe they would have continued to publish everything in FR. Instead we have FR, Eberron, Ravnica, Theros, Wildemount (even if they didn't directly oversee it's creation) and now Ravenloft. So "standard" D&D, magi-tech, urban campaigns, Greek mythology, a different spin on standard D&D, gothic horror.
