Lobbies / Private Servers
I'm sure you've heard this 10,000x, but can you add actual private servers and lobbies? It's a normal feature of almost every FPS game, and has been since the first iteration of the Battlefield franchise.
I'll give an experience.
Playing Battlefield 4 on a certain server with the same people multiple days a week. They got to know me, one sent me money to buy more alcohol (lol).
In Battlefield 1 (the ww1 game) I constantly played on the same servers with people and we would joke around and have fun in all-talk, because over time me all got to know eachother.
That's part of what makes FPS games so great. The connections you can make.
And while my examples are weird, it just goes to show you don't know how life will work out if you don't try.
Thanks.
