Old news. It is technically possible, but a lot of red tape from Micro$oft and $ony prevents this.
That's what I'm saying, I just don't see why they disallow it if it is a single-player game and should therefore be suited to what you like.
It's not looked down upon. It's just impossible to moderate on consoles. And since consoles don't have the freedom of a PC you have the potential to break your game beyond repair. Mods often have conflicts and you couldn't release them on consoles unless they were guaranteed to work.
I was permanently banned for modding a Fallout 3 save years back, which leads me to believe they don't like any sort of modding. That is true, but I've yet to ruin my game from modding. I've corrupted a couple saves but that's due to forgetfulness. Mods do tend to raise a few red flags on occasions but that's why I added the bit where if Bethesda "moderated" what mods were and were not safe. I believe it could be done, and would give console players something to look forward to.
It would be similar to add-ons like Battlehorn Castle and Frostcrag Spire, just user-created and hopefully free. I do remember Bethesda saying they were going to be creating larger DLC's opposed to small add-ons, so why can't the community help out in terms of small add-ons? They do it well enough on the PC.
Which is what DLCs are for,
Seriously unless you can come up with a way of someone opening up a site that moderates and picks selected mods that have no viruses and 110% chance of working without someone paying for either it be MS sony or beth it won't happen. Nexus isn't full proof and some mods will break the game if not the system entirely if implemented on a 360 or PS3 such as Texture packs and some overhauls.
This is kind of the point I'm trying to get at. The community could do their usual mod creation, and if the mod has enough positive feedback and is very popular, Bethesda could work on converting it for console players. I remember Project Paradise for Oblivion, how it brought a few PC mods to retail Xbox's. I got it working on mine and I even added a few things, so it's possible on retails.
On the topic of retails, that brings me to J-tag consoles that can run unsigned code. There were a lot of console modders who got texture packs, environment overhauls, custom spells, dual-wielding, etc. all on their Xbox. I can find the videos for you if you're interested.
