Aion

This is a typical mmorpg game that I used to play a lot. It is for the pc and is very much like world of warcraft, but without the pay as it recently became free to play. You can customize your characters looks and skills. You go through the game defeating monsters and completing quests to level up. It requires patience for a lot of the leveling can take a while and a lot of monster killing. You can buy new gear and equipment and even pets to accompany you.
