Metro 2033 Ten Years On | Is it a Classic ?

Metro 2033 is a FPS survival horror game set during a nuclear winter, taking place in the Moscow underground where humanity has found refuge in the metro stations and tunnels. It sets you on a tight linear track, pun intended, and will have you crawl through maintenance tunnels, fight mutants, Nazis, Communists, scrounge resources from dead bodies, barely survive on the surface and deal with paranormal and psychic events...but is it a classic?
