Sorry I triggered you with that off-handed use of terminology. But, y'know, ignore everything before the "but"
but even in schemas where popularity or commercial success are all that matter, things closely comparable to TTRPGs, like CRPGs, MMOs, CRPGs, and the like are much more popular & commercially successful than D&D.As successful as 5e/80s D&D has been compared to non-fad D&D, or the extremely niche rest of the TTRPG hobby that D&D accidentally created, and still utterly dominates, it (or TTRPGs generally) may not be as popular as they could have been, if D&D had not boxed itself into the narrow design parameters WotC is working with, today, or, indeed, if the hobby had been accidentally founded by some other nigh-RPG wargame (or actualy RPG), instead of D&D.
Seriously?
D&D (and TTRPGs) is a hobby that requires both a significant investment of time, the ability to get a number of people together, and (until recently) the ability to get them together in the same place. Not to mention that it's a completely different field of entertainment.
Arguing that the most successful TTRPG isn't successful because ... it isn't as successful as computer games, which make more money than the box office returns of movies, is not just engaging in some type of counter-factual bizarre hypotheticals, it's moving the goalposts so far in this conversation that they might as well be on Alpha Centauri for a field goal.
Sure. If pigs had wings, maybe bacon would fly into my mouth. But I'm not sure that the concept has any relevance to an actual discussion.
