Which sentence is correct? Anyone who wants a copy of the game may have it for their video library or Anyone who wants a copy of the game may have it for his or her video library?

Anyone = singular or plural?? (hint: "one" in the word)

Therefore you need to have later pronoun(s) match --

their = plural

his or her = singular

What do you think?
Anyone is singular, so the pronoun that refers to it must also be singular.
