Why is that impossible? Create the post in !reddeadredemption@lemmy.ml, or !gta6@lemmy.ml or !fortnite@lemmy.ml (those are the games OP keeps harping on) or whatever game they’re interested in.

I guess if there’s no existing community, that’s an issue. Create one, then. Post the hyper-specific question into that new community, and then go post an announcement of the community in the broader games communities and let people interested naturally filter in.

I’m not a Lemmy expert by any means, I’m just suggesting ways to engage with people that seems to me like it’d be more constructive and likely to be appreciated. 🤷
