Appreciate you being upfront about that, and yeah, you're right, this would be a paid service, I'd rather be clear about that too than build false expectations on either side.
On the Steam and Apple App Store goal though, that's a solid long term plan, but it's worth knowing that getting listed on those platforms is really just step one, the bigger challenge after that is actually getting the game in front of the right audience once it's there. Both Steam and the App Store are massive, crowded spaces, having a great game live on them doesn't automatically mean people find it, discovery mostly happens through outside visibility, social content, word of mouth, creators talking about it, that funnels people toward the store page, not the other way around.
That's really where short-form video and consistent social presence come in, building an audience now on modern platforms means by the time Vault of Seraphim XL reaches Steam or Apple, there's already a group of people actively looking for it instead of starting from zero once it lands there. Happy to put together a few ideas on how that could look specifically for your platform goals if you're interested.
