Would Like A Persistent Battlefield Game.
With the upcoming Battlefield 6 and it's free 2 play mode possibly having a BR (very likely), I suggest something else entirely.
To me Battle Royal was fun in 2017 to 2019 (Apex Legends), but it got old quickly. I would rather enjoy a persistent server type game more to where it just continues to run while I'm not in the game.
Base building, scavenging, PVP, non-shooting NPC's, wildlife, dynamic weather, vehicles, modding community, destruction, groups.
To me, a huge ever changing world around the Battlefield 3 theme could work in this type of mode if done right. It just needs the right scale to work. This upcoming Battlefield 6 does have a nice scale (everything else I don't really like), so if the engine could handle it, I think EA should test it.
