Ironically for a post complaining about reading comprehension, but you misrepresented the original post you’re talking about. Even have the classic “quotation marks around a thing that was never said” in the title.

First, and perhaps most obvious, this wasn’t “everyone”. This was one person, and they didn’t get many upvotes. When I recommend a TTRPG, for example, I’m recommending Genesys (like someone else did).

Second, they weren’t saying to homebrew old editions of D&D. They were saying you don’t need to homebrew at all. At most, they said you could reflavour something in 4th edition. Their entire point was that you don’t need to homebrew when you can just find a system that already has what you would have homebrewed in.

Third, they were suggesting this as an alternative to homebrewing specific material into D&D 5e. Pathfinder can provide the experience of “5e with time travel” that you wanted without any modifications. BitD is so different from 5e that it can’t.

You are, however, correct that they did backtrack. I’ll put this down to poorly explaining their argument to start with, as they downplayed the “5e but better” games in their first comment while that was really their entire point.

Personally, I like homebrewing. It’s fun to tinker with the rules and materials. But there’s also an argument to not repeat work someone else has already done.

Instead of making your own homebrew, just play someone else’s homebrew that they’ve already balanced and playtested.

“Try more games” is great advice, and it’s always good to expand your horizons, but at some point it stopped being actual advice and became the catchphrase of people who just can’t handle the idea that someone would choose to play D&D.

I want more people to play Changeling: the Dreaming, or older World of Darkness games.
