So I finally found myself in the Saugus Iron Works the other day and got myself involved with the quest with the raiders there who call themselves the Forged. I thought it was a neat enough idea for a raider gang and it was quite funny going through the terminal seeing how many people the ring leader "fed to the forge" and I liked that nice little climix in the end where you're seeing the farmer's son go through with this ultimatum. But I feel this was a missed opportunity to have added something better to this quest and location than just some pyromaniacs.
I felt this could have been the perfect time to actually bring up raiders from the Pitt and make their appearance in the Commonwealth. It's said this group of raiders have only just moved into the area and are recruiting so I think that would have been a good enough indication that these raiders are from elsewhere. They seemed to have given the farmer's son the impression they were going to be raiding outside the Commonwealth as well, as if they were from outside the Commonwealth.
On top of that, well, look at the location they moved into. If that doesn't remind someone of the Pitt then I don't know what does. I know it's not a steel works, but I'm sure some reason could have been made as to why they were interested in that location than just the "they like fire" reason the Forged has.
Lastly, these raiders felt more well-equipped than most raiders with just about all of them wearing cage armor and their leader being in a suit of power armor. I know there are random gangs of raiders out in the Commonwealth that can use power armor anyway, but I felt this could have been a nice way to make out that Ashur had trained some of his raiders in using power armor and those in power armor were some of his more elite raiders in his ranks.
Had all of this been done to have the Pitt raiders in place of the Forged, it would have been a great time to tell us more about what has been going on in the Pitt in the last ten years. The Forged leader had already logged entries in one of the terminals, and this could have been the same if they were from the Pitt and they had logged journal entries of their time in the Pitt and their journey to the Commonwealth.
The Pitt was probably my most favorite thing added to the Fallout universe from Fallout 3, and among one of my favorite settings in the series. I am always wanting to see and hear more from them.
