That's not an argument of quality at all. Just an admission of wanting to go with the status quo for the sake of it.
You already have sunk costs, and have to spend WAY more money, by going along with 2024 D&D. Your older D&D books are invalidated and you now have to buy many more to keep up.
So what actually is there to be "invested" in here, that can't instead be done with a better product? It's already a new ruleset that has to be adopted. You're simply choosing to adopt the rules of a game that happens to be from the same company. It's like if a restaurant started selling chicken nuggets instead hamburgers, while deleting all the coupons you received from buying hamburgers, and you blindly insisting the chicken nuggets must be the best thing to eat, since you formerly bought hamburgers there.
This is you putting words in someone's mouth, yet again. Also, people don't know what they like best if they don't experience alternatives. If people truly feel D&D is the best, having come to that conclusion from playing many other games, then sure. But it's frequently the case that people have only experienced a sliver of what exists.
I'm not putting words in your mouth. I wrote that you are
in effect calling people stupid sheep.
Do you not see that you are doing that? When you state, as you have reiterated here, that people are simply going with D&D because we don't know better than to just "go with the status quo for the sake of it", what exactly do you think you are implying, other than that we are stupid sheep? Do you not see that your framing is deeply insulting?
Well, it is. Which is why many, many people have responded negatively.
For your information, I am a professional with a masters degree. I have played many, many different TTRPGs in my forty+ years of serious gaming. I even have a publication credit for being the principal designer of an educational game (
Up the Creek: The Salmon Survival Game). So I'm not some rube who stumbled across D&D and has never looked elsewhere. I think similar goes for most folks on this forum.
I am also familiar with the DC20 system. I very much enjoy the Dimension 20 crew, and appreciate their perspective on it, and I've kept track of it's development, as I do with many TTRPGs.
So maybe, just maybe, people disagree with you for reasons other than being ignorant. Maybe we are just as smart, just as informed as you, and have still come to different conclusions. That's how opinions work.
