Epic generally works fine through Heroic launcher. Though I’ve had some occasional problems with Heroic and in those cases Lutris running the Windows Epic Game Store Launcher solved every time. Steam and Proton are still the easiest plug n play though.
The older Tribes titles if you’re into classic arena shooters. Tribes 2 had some maps and modes that were more Battlefield-esque too. The old Age of series were excellent LAN games as well (empires/mythology). These are PC titles and I’m not sure of your target platform.
