Halo, God of War, Ghost of Tsushima, CoD, Forza, Gran Turismo, The Last of Us, Uncharted, Watchdogs, Battlefield, Elden Ring, Assassin's Creed, FIFA, Madden, Far Cry, Elder Scrolls, Fallout, Starfield, Diablo, Overwatch... none of those use UE, and that's just the ones I can name off the top of my head.
