While a bit stale, this transcript of JC Herz, at some high-falutin' conference in Amsterdam, is very on point regarding mod culture in games.
Actually, this is a complete vanity link because I've been locked in a room with JC discussing games on occasion. There's no way I could ever verify myself as inspiration, but at one point within her earshot I remember saying, "There's gonna be a whole generation of kids who expect everything to be moddable!"
