I have a published Itch store page (though not indexed yet), and I just completed (but didn't publish) my Steam store page. The one reason I'm holding back is that I'm still working on my trailer, though it may take a while. I'm eager to publish my Steam page so I can have more time to get more of those sweet sweet wishlists, but without a trailer I fear that maybe it might not make the first impression that I'm aiming for. So in your opinions, what would be best:
a) Publish your store page ASAP for maximum wishlist time then upload trailer as soon as it's complete.
b) Wait for the trailer to be done then publish your store page.
