Hello people, English is not my primary language, so it is just natural I make such basic questions...

Is it correct to say "An RPG" (where RPG could be the common "Role-Playing Game" term), or do I have to say "A RPG", without the "n"? Considering RPG does not begin with a vowel... yet, it sounds like it does.
