I don't remember the series a ton specifically, nothing that stands out, but I think I played a good portion of them over the years from the PS2 and on as I was big into both that and the Call of Duty games for a good while. I even liked the reboot they did to try and capture some of Call of Duty's thunder, which honestly I thought was quite good and I liked the multiplayer more than I did Call of Duty, as at the time we were getting Black Ops, which had a super awful PC launch, and Modern Warfare 3, which I had no interest in, the series basically dying off for me, so the first game was a cool time. Don't remember if it had a good singleplayer, honestly, most military shooters kinda post Call of Duty 4 I don't think were super great as far as stories go (Battlefield: Bad Company being an exception), like I don't care if you add big name actors or make it as serious as can be, they are kinda one and done things, it's always about the multiplayer for me.
I don't remember Warfighter at all, the sequel to the reboot, I know it didn't do well, and looking at my Origins library, it looks like I don't even own it, meaning I never played it. Wouldn't have been played on console either as I stopped playing FPS games for the most on console after the Xbox 360. Some exceptions here and there, but I need a mouse to really enjoy an FPS game.
