If you can think of some clear and concrete standards to support your suggestion, though, I would be interested in hearing them.
The goal would be to separate content in a better way. Make a Meme game? Post it in the meme/joke section. Your first unity rolla-ball tutorial project? Post it in a showoff section. You want to make the thousandth among us clone with no twist or unique take? Don't post it in the new multiplayer games. Post it in your personal projects or show off section. You actually made a quality original game? Go ahead and post it in the category that describes your game the most and enjoy being in the fresh new games with other quality original games. That's what I mean by curating.
Does it have to be on par with Shovel Knight, or is an ugly platformer with one level and no music OK?
The ugly plat-former with no sound should be in your personal projects or a showoff section. Not with shovel knight or with other polished games. (By other polished games, I don't mean only well known ones)
My point is, prototypes should be with prototypes, fully polished games should be with fully polished games, memes should be with memes, low quality or beginner projects should be with beginner projects. Is that any clearer?
If I make a meme game , this game should not be tagged with anything other than meme. It shouldn't be with polished action games or polished multiplayer games or serious game prototypes.
