Depends on how you define new. Battle Royale could be viewed as just an evolution of the arena shooter genre where you expand the map and the player count to the maximum with the “arena pickups” being randomized. Or it could be viewed as something new because it fundamentally plays differently. IMO taking things that have been done before and combining them into something that hasn’t been done before is still creating something new.

And if you want really fresh ideas, there’s always the indie scene. I will always point my finger at Noita and the absolutely insane wand/spellcrafting system which is probably the most wizarding experience you can have. You can literally create a wand that (and I’m significantly simplifying the process because honestly I have no idea how that actually works) summons a deer into a parallel world and then swaps your location with the deer making you teleport into a parallel world. And no, that is most likely not the intended use of any of the spells that go into that wand. The devs themselves were probably trying to figure out if that’s a feature or a bug.
