Latter Earth is just the "default" setting. There's a chapter titled Creating Your Campaign that has advice for world building from the top down and some magical traditions come with advice for running them in different settings. Classes are kept generic enough to work in pretty much any setting and there's advice for making new races
PbtA is more of an engine than a game. You can technically run anything with it if you don't mind making entire play books for each setting. At that point you're basically making a new game
I'd recommend taking a look at BESM though. It's more anime themed, but it's a competent system with a lot of flexibility built in. Magic kinda has rules, but it's treated like any other power your character can have. You buy the effects and limitations of your spells when you make or improve your characters
Another good option is WOIN. Technically it's 3 games (OLD, NEW, and NOW), but all three books are fully compatible with each other by design and the medieval fantasy book (OLD) has rules for magic and creating a spellcaster. The 80s action movie book (NOW) has rules for firearms and mutant powers, and the space faring sci-fi book (NEW) has rules for cybernetics and psychic powers
From the games you mentioned, the most flexible ones (that I've actually read) are: Risus, Fate (same as fudge), Savage Worlds, Whitehack, Freeform Universal, Hero System, and Worlds Without Number (mostly compatible with Stars Without Number btw). Of those, the fastest combat is probably Freeform Universal. Savage Worlds is fairly fast too, but more tactical. Worlds Without Number probably has the most consistent combat pacing though
There's also the reaction from other developers claiming that the game "sets an unrealistic standard for what to expect out of a game" despite it being exactly what people want from a triple A studio. Just a complete, well made, functional game with no microtransactions
Idk, I don't even pay that much for kosher food and the smallest and cheapest kosher burger I've ever seen cost $5 with $10 being closer to the average
Sounds good to me. My only real complaint about solar panels is the space they occupy. That complaint goes away if that space can also be used for crops. It's a win/win
I know it's not quite the same, but Song of the Beast by Carol Berg is kinda like this. The book starts after the main character is released from a 20 year prison sentence and he's trying to find out why he was in there in the first place
Technically you still use weapons but you start with a 100% damage penalty and get points and experience for leaving as many monsters as possible alive
