I absolutely love this. Have y'all been collecting your advice? I'd love to learn what has and hasn't worked so far for your projects.
Where else can I buy an ethical ad to find my potential players? My best idea so far has been to purchase an advertisement on some of those podcasts I mentioned, since they are just reading a sentence or three during their normal recording so there is no additional tracking really going on that I'm aware of.
You four would be a great option for reaching other developers. Imagine if you could search for ethical advertisers by category with links to reach out. Does this exist already?
I would suggest looking at communities and websites that are targeting fantasy novels and Tabletop RPGs. You're headed in the right direction.
Unfortunately that solution doesn't exist yet.
