Tribes 2 with modern graphics for modern platforms, and maybe an Apex Legends-like Battle Royale mode. I don't think that there has ever been a better multiplayer FPS. When you're used to jetpacks and skiing, most other FPS feel slow. And there is nothing as elegant as killing with slow ballistic projectiles like the Spin Fusor.
Apex Legends has got some of the aspects that made T2 so great, especially if you play Valkyrie (Apex's only flying character), but the weapons are not as much fun and you're wasting too much time on looting.
