Wait. Is everything from LemmyNSFW.com NOT auto-tagged, or is that community also on another instance?

Anything that can be made playable in the terminal like so is gods' own work ... but someone needs to teach that poor coder about subroutines, and the various gameplay engines(AI/CPU opponents, and move validation) that exist already.
Hell, the UI/UX work may be in place already, but some wheels can be rewarding to reinvent, even if only to learn them from the ground up.
Gimme the option to show only actual NSFW-tagged posts for starters, not just every post that happens to mention the concept...
Personally, I have not setup an app yet. Web version is all I know so far, and I'm coming from old.reddit as my previous standby anyways. I mistakenly paid for Fedilab, only to find it doesn't support Lemmy, or at least not the instance I'm on.
Lemmy web does what I want and expect so far, although subscribing across instances could be smoother.
Alernately, a convenient way to view only SWF posts, both SFW & NSFW posts, or only NSFW posts ...
For that last, and I am sure many other uses, a way to only see subscribed communities from a given instance - we shouldn't have to create new accounts on every instance we consider useful enough to do this, and for those instances, they shouldn't have to bear the burden of everyone who considers them so useful creating accounts with them and visitting them directly every time the fancy strikes; That's effectively just punishing the most useful and popular instances with additional server costs.
EDIT: Forgot to mention: Lemmyverse.com community search already handles NSFW exactly as I am suggesting.
