I'm guessing a lot here but these types of titles typically ship with very high res assets of various types. In terms of textures it's not just one for each entity, but often a complete stack of textures like albedo, detail map, normal map, ambient occlusion map etc. All in 4K or possibly higher these day Then there's high res audio, UI textures, massive terrain textures (again stacked), skybox textures (HDR cubemaps in high res), bits and bobs, weapons, animations, the list goes on. Assets for these types of games are heavy.
