Arcane
The Ace Combat series of video games is known for solving the problem of having modern military powers fight without everyone just nuking eachother and letting the player slaughter hundreds without concern of triggering an international outrage by using its own unique planet, with its own continents and countries but mostly contemporary technology (some a bit ahead, while others, most notably nuclear weapons, are far behind). Has there ever been a tabletop game that did this? I can think of plenty of fantasy settings, plenty of contemporary/recent past settings that are "Our Earth but X", and a few sci-fi worlds, but I can't think of any original settings that only have roughly earth technology and no magic. Are there any in the medium?
