@hellpe Well the problem is, these aren't even really games, they're super nerdy apps that are literally useless unless you know how to pirate retro games.
But yes, I agree that they're way too prominent on Flathub at the moment.
@delight_aug @tbernard I did discover retro gaming through these (indeed super nerdy) apps myself, however I agree with Tobias that the way they're featured among all other games makes for a bad user experience on an app store such as Flathub.
