No, it doesn't, he's retarded.
And the answer is obviously because they're mostly all terrible amateurs who think that hiding inside of them is an "expert game designer" that they've been somehow cultivating just by playing video games and watching Extra Credits. They don't realize that actual game design is hard work and takes a lot of studying and practice to get right. It's a skill, and it's one that they don't have.
You're right, the worst problem they have is excess. They can't gauge what is "enough", and have no idea of the concept "less is more". If they had ever done any sort of real art, engineering, music composition, amateur film, or anything at all that takes creativity and skill, they'd know this and know that good art and design is about balancing what you put down and not giving your consumer a terrible sense of sensory overload. It's not like you have to be minimalist, but you do have to practice some restraint and hone it into something clean.
Most of the people making game mods and maps are talentless and actually have no hobbies outside of playing video games and watching superhero movies, so it's really not surprising that they also fuck up the one thing that they assume they must be good at.
