Nintendo's eShop is a mess. Because it puts the shovelware next to everything else.

Steam isn't so bad. I rarely find it unless I'm in the dark recesses of a tag. And whenever im curious if what shovelware exists, I just visit indiegala.

Console certifications only check that a game is functional and meets platform requirements (like achievements, peripheral support, accessibility).

They’re there to ensure a game works and won’t brick any systems or steal bank details etc. They don’t typically check that a game is ‘good’, since it’s so subjective.

There's always plenty of garbage on Steam and itch.io
