Steam is in a weird position as a marketplace. It has to serve mainstream developers, indie but relatively large developers or at least polished games (the kind of thing that would've past steam greenlight fairly quickly back when that was around) and tiny, single indivial indies who may or may not put out something nobody else will (occasionally slop clones) (the kind of thing that've taken a while to pass greenlight). I'm not sure if and how they can create a system that works for everyone. A $1k ceiling is maybe the worst idea. It hurts poor indies but not ai slop studios as much. It's possible that the return of some greenlight-esque curattioj could work, but it'd be devastating if your game got rejected as a false positive for ai slop or anything.
