Depends, Battlefront has on foot combat and decent flying

Squadrons has more improved flying but no on foot combat

Both have Multiplayer but Battlefront (from my experience anyway) has much more consistent and active players

Get Star Wars: Battlefront II and the conversion pack. And check out the other mods; despite being nineteen years old, it still as an active modding scene.

Battlefront well depends on which one you get

I say the newer ones for sure

I would say Battlefront. Squadrons is a really fun flight sim, but the multiplayer lobbies are practically nonexistent
