Its just i dont see anything to do with a nation. Police is on its own, Institute works with police only on Synth Retention Bureau. Commonwealth itself isnt like NCR. But that just my opinion.
You're right in that it doesn't say it's a nation, but I think it's pretty clear they are. Mostly because of the aforementioned police force, the fact that in the Replicated Man quest, it was mentioned that the Commonwealth,
not the Institute, tried to cover-up the fact that an android was on the run, and because the area is named after the Commonwealth of Massachusetts with "of Massachusetts" removed, hinting that it is not simply a lawless wasteland like D.C. is.
Also, on the wiki page for the Commonwealth, it says that the Synth Retention Bureau only captures escaped androids from the Institute, when it actuality this is not the case. Like Harkness who worked for the Synth Retention Bureau, androids seem to be integrated into the society of the Commonwealth. I would attempt to correct the wiki however the moderators there are strict to the point of actually making it difficult to add anything new, as if they don't want to see any previously unknown lore added. I was lucky to get the small amount of information I did on the wiki.
Am I the only one who thinks that the institute is ridiculous?
Why?
