SWAT4 had more a realistic approach to police shit
I wouldn't call a raid on barricaded militant, fanatic environmentalists any more realistic than the shit you see in RoN.
In fact reading over the mission summaries (I haven't SWAT 4 in like nearly a decade, so bear with me) I can draw a lot of connections between the originals and RoN's levels.
Red Library offices -> Mindjot (less so the content, more the setting i think are somewhat analagous)
Food wall -> Kawayu Beach (illegal firearms)
A-bomb -> Neon (this one in particular, I feel like A-bomb felt kinda held back by its engine.)
Children of Tarrone -> Valley of the Dolls (Dead children in the basement)
St. Micheals -> Relapse (terrorists in a medical center)
Old Granite hotel -> Sins of the Father (hotel)
Edit: accidentally hit post, whoops
I could go on, but I think you get the point. These aren't one-to-one, and that's not really my point im making here.
I legitimately wonder how many people who say that SWAT 4 is somehow "more realistic" have actually played this game they glaze so hard. it is common that I see people point out the locations of RoN's levels claiming to be "less realistic" or that "SWAT teams never see this much action", but it never made sense to me when a considerable amount of its levels are retreading its own ground. I feel like that would be pointed out by people more if they actually played the game.
As for the content of the levels, I guess there's a point to be made, but Neon, for example,
is directly inspired by real life events, and it is clear to me that they are trying to pay respect to the reality of the incidents. A lot of people died those days, and that's just the reality of the situation. I don't understand how trying to be faithful to incidents like that in a game that is clearly trying to pay homage to police work can be brushed off as "edgy for the sake of it" when it clearly wants to highlight the horrific nature of the job.
And some are clearly here for the sake of the wider narrative with the MLO, but I wouldn't say thats any worse than SWAT 4 putting in a mission where a Terror cell raids a Biotech Research station to make a point about Biotechnology as a whole. (I liked that mission, FWIW.)
