I should tell you what role-playing games (or simply role games) are. There are some different kind of role games, like:
-Role videogames: you and some friends switch on your consoles and decided what are you going to be, from a healer to a assasin.
-Role tablegames: you set your cardboard table-top and choose your favorite character, your friends and you have to reach the objectives.
-Role games (based on imagination), or book role games: these are which I like the most, someone is the master and prepares a meeting. The players have to beat the difficulties that the master proposes to them. In my opinion, you will enjoy more them because it is a personal experience prepared to you, so the master will include personal things that you won't see in other role game.
Examples and recommanations:
If you want to try role videogames you have tons of them:
-For lonely players who love calm and paused combats you should try an RPG like Fallout 3, Dragon Quest VIII or Final Fantasy VI.
-For coperative, but not very experienced players, you have some free games like Metin II or Team Fortress 2.
-For hard players, who have plenty of free time there are Diablo III and World of Warcraft.

If you want to try role tablegames there are some which I have personaly played and enjoyed:
Catan (interesting game about colonizing an island, for all kind of people)
Scape from Silver City (for Zombies lovers, your friendship will be in danger)
Warhammer (for experienced people with free time, fantasy battles everywhere)
If you want to try book role games you should try:
Path Finder (the one you should first play)
Dragons and Dungeons (the most known and the funniest, I think)
*For playing this kind of games you must have some interested friends, an experienced master, some dices and a complete day to spend in the game.
