In halo 3 multiplayer you have a skill rating next to your gamer tag. 50 is the highest possible skill rating.
The age rating for halo combat evolved start from 18 - infinite, though you have to be old enough to buy it, kids as young as six has been known to play this game. I hope this has helped.
It is rated 16+, however I do not believe that this age rating is to stop you from buying the game, just to warn that it may be offensive to some.

ESRB rated it M-Mature due to violence, language, and blood & gore.
it was banned because the highest rating that a game can go in Australia is 15 yrs old. if a game, like odst, is m rated it is banned because the m rating is 17 and older. anything over t in Australia is banned
Since Halo 3 is rated M (Mature), it is suitable for persons aged 17 and older.
