I guess that make sense in that context. A game can have many content developers, and a content developer can develop content for many games. Although it would still work like that if you exclude user-generated content so it would still be many-to-many.
I don't know why they're using database development terminology to describe a product meant to simplify things.
Every time you point out that something is an opinion Jesus shoots a kitten in the face.
wait i dont understand any of this really, but is he saying that people who have modded the game make more money off of it than the actual devs, or is this done by people involved with the regular game?
