When you launch something on #Steam expect a flood on mails from "streamers" who want a free game key for a "review"
Chances are big those keys end up on marketplaces for "cheap games" and such
If these super popular streamers cannot pay the 0,99 cents and 4,99 for my game I'd rather they do not review it
It would be fun if one of my games got popular but it's not a requirement
