thats not what I meant. I mean if sony gave bethesda some money I think it would be possible to download mods via psn store or something along those lines
Actually, it's Sony and Microsoft that forbids it, Bethesda itself has nothing against it. According to console manufacturers, allowing user-created (technically, any non-homologated) material is a potential security loophole. Which is true, actually, because it could allow you to eg change your records and cheat on the achievements, and we all know how important showing off those thingies is for (most) console users... -_-
EDIT: There's also the more palpable risk of piracy, though that's not so simple.
