Open World/Sandbox and Camp Open/Sandbox World all the way.
Other genres that you didn't think were open World will advance to this game design. Look at Planetside MMO Open World. Assassins Creed traditional Open World. FFXV Open World RPG. NFS Rivals is considered Open World or more so than Hot Pursuit the developers claim. Watchdogs, Uncharted, maybe a sub-genre named Camp-Open World/Horror like an Evil Within title.
FPS games still have the potential to sell more copies individually over Open world/Camp Open/Sandbox World games though, but lets see which one gives CoD the run for its money besides GTA6 this gen.
