Is black ops appropriate for a 14 year old?

yes and no. the campaign has alot of language in it and the blood spews everywhere which is not exactly a good experience. however, most people play online matches which are extremely fun. ther's still some blood but at least it's not spewing out. so i'd say this part is pretty decent for a 13 year old. there are some people who swear online though. they can be muted, however. all in all, if you're not a control freak-parent, it should run smoothly. trust me this game would still b fun if it was water guns.
