I'd play that game too. It'd be dark, controversial, and a political minefield, but I think a story-driven FPS set in a civil warring 2030 America would be awesome. The usual stories in CoD or Battlefield of USA military vs insurgents who are vaguely slavic or vaguely middle eastern have gotten stale for me - I'd love to see what game designers think all-American militia battles in NYC or Miami could feel like.
Again, it'd be super controversial and will probably never get made, but I'd play a game like that.
If you haven’t tried it yet, I think Far Cry 5 fits your desired description somewhat. I only played it for the first time recently despite it coming out several years ago and it was a little “too real” at times.
It has over the top moments (like GTA) but I think the story is compelling and it’s not hard to see the parallels to modern day groups and events.
I haven't really played a Far Cry game since #3 and knew almost nothing about #5. Just did some reading about it and sounds almost exactly like what I was describing up there, hahah. Given I'll be spending at least a few months off work from an injury, playing #5 sounds like the perfect way to spend some winter afternoons. Thanks for the suggestion, I'll definitely give it a shot!
