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.

I usually recommend people try games that are "Not D&D or a close relative of it." Blades is not a close relative of D&D. It's a close relative of PbtA.

BitD in no way resembles the statisticians' stroganoff that is oldschool D&D. Step away from the pipe.

"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.

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

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

Are you are suggesting Blades in the Dark is some kind of derivative of D&D? If so, that is a very hot take. And even if you like 5e, imo, Pathfinder 2e is right there doing the same thing but better.

Is there another sub for non-meme ttrpg discussion?

I'll say it here regardless - Feng Shui is my favourite system that's not Blades or DnD or derivates.

The whole premise is based around Hong Kong style action flicks. Most enemies have one hit point. If you hit, they go down. If you describe your action well, you get a bonus- instead of saying "I kick the guy", players are encouraged to say "I leap from the balcony, swing from the tapestry, and fly-kick the guy in the head". The setting includes four distinct time periods, so you can travel from a cyberpunk future to a colonial history between sessions. It's fast, it lends itself to simple plots, and it's fun to be awesome.

Extremely funny that you're so upset you made a meme to vent over your lack of imagination, so just to be a complete asshole about this, the fact that you're not running Blades until tomorrow very literally means you haven't actually played it yet.

Wait, it doesn’t count because BitD is “just a D&D homebrew”? According to whom?

I'll correct that then, try GURPS or how about F.A.T.A.L
