Person of Interest
"There is a Machine, that watches you every hour of every day. I know because I built it. It was supposed to report terrorist threats, but it sees everything. Ordinary crimes against ordinary people..." - Mr. Finch, Person of Interest
Wait, so who's who?
In a sense, it's white-and-grey. The government wasn't necessarily pure evil, but they could order hits that were unjust and get away with it because it didn't hit the news back in 2002. There was no pulled punches though, it showed that the NSA is not above criticism in-story.
The main characters, though, are ex-government employees, working (secretly) with the NSA's secret surveillance AI to prevent lethal crimes (in ways that prevent murder, not ways that get people arrested for things they haven't done yet). Other characters were added as the story progressed, with almost everyone (but the Machine and one of the female characters introduced after the setup period) in the main cast dying by the end. Fortunately, they don't go quietly into the night, and many lives are saved because it happens.
Is there a bad guy who is recurring then?
Not in the traditional sense. The NSA and other government agencies were a grey-morality version of this once the plot got rolling, but that was replaced by the big bad in the final seasons, Samaritan (the evil "anti-Machine" AI that was told it was god and actually believed it).
There was a guy called "The Ghost" who did evil stuff and managed to survive encountering the Machine once by staying off the radar, but he is killed by a less evil but more practically-minded recurring villain whose name I will not spoil. I also won't spoil it, but both the Ghost and the villain who had standards don't get the chance to become a major threat despite standing a decent chance.
Person of Interest influence on Glitch Techs x RP
If ctOS and Glitches exist, of course there's influence from this. When Watch_dogs came out, the only inspiration with a similar aesthetic was this one. The others... Cyberpunk 2020, ReBoot, Fallout: New Vegas, MegaMan Battle Network 6 and MegaMan Star Force 3, Portal 2, Grand Theft Auto V, and Wreck-It Ralph... all have very different looks, or... like Glitch Techs, THE FINALS, GameDec and any others not listed prior... had not yet been publicly released.
