I still miss Battlefield 2. There is really nothing like it today, not even close. The dynamics with squads and a commander and A+ physics and overall game balance remain unmatched for all FPS games.
Fortnite, PUBG, COD, all are disgraceful in comparison.
Check out BF2Hub. The community isn't big, but you can generally find a server or three with real players in it (just look for players with a ping; 0 ping means a bot).
I miss the squad gameplay of Battlefield 2 too. It hasn't been replicated since, in my opinion, and subsequent Battlefield titles changed the classes and made the available loadout options too flexible to require specialized play.
BF2 was great, BF3 was definitely better, not that there was anything at fault of BF2.
I disagree with Fortnite and PUBG, whilst PUBG is a little clunky it did usher in a completely new game style AND importantly introduced much better situational audio which other games didn't have.
