why would frontlines be rated t when halo 3 is rated m?

[George B]

why would frontlines: fuel of war be rated t when halo 3 is rated m? i mean multiplayer in both hve basically the same amount of blood. in fact frontlines might have more! ive never played campaign in halo 3.

It probably has to do with language vulgar and + there may be more blood in frontlines but I bet it doesn't have much, or any gore, while Halo is loaded with blood, gore & swearing.
