Does anyone agree with me in thinking that the Brotherhood of steel and Enclave should play a much larger part in fallout new vegas,
To what end? Out west, both groups power has been totally broken. Heck, look at the remnants: Five old men who're trying to blend into society lest they be found and killed/run out of town. In the East the Brotherhood and Enclave might be powerful, but there's many thousands of miles between DC and the Mojave.
also i think some of the weapons and armor people have made for mods should be included in the DLC's such as the gauss minigun and t57c power armor both
There are significant legal hurdles that prevent this. The closest you can get without opening yourself up to legal issues is being "inspired" by mods, like the weapon mod kit -> implementation of weapon mods in New Vegas situation.
i think are fan made but would make absolutely brilliant aditions to the game itself.And having the game for the xbox 360 means i wouldnt be able to get them any other way and im sure there are plenty of people who agree that some of the mods should be used in the actual game and included in the DLC's so people not on PC can get these awsome creations.
They are brilliant additions to the game. They're awesome and seriously enrich my New Vegas experience. Unfortunately, releasing them in the manner you suggest isn't practical. Bethesda and Obsidian are both aware of how much mods add to the game, yet they've never released a DLC mod compilation pack like you suggest.
