Lets pretend Microsoft and Sony got high and said “OK”
Top 5 mods would ruin your game and maybe turn your console into a neat yet bulky paperweight
This. This is the trillionth time this thread has come up - not just for Skyrim, but for Morrowind, Oblivion, Fallout 3 and NV as well.
Mods on a console would not work.The modder would need to stay within the consoles hardware limitations whilst optimizing the mod, not to mention the inevitable incompatibilities, no way to update the mods, lack of access to file structure, and the general closed nature of the consoles. It's critical to have full access to the files whilst modding, as well as full control over whether or not the .esms/.esps are active or not. This way, if something becomes corrupt or broken (which it does) it's very easy to deactivate the mod until a solution can be worked out. There is no way you could ever do something like this on a console.
The only way this would work would be if Bethesda tested each mod as if it were official, gave the modders strict guidelines to stay within console limitations, and most importantly came up with a way to manage the mods' load order. Again, the latter will not/could not happen for the reasons stated above, and thus, mods on the consoles wouldn't work.
