First let me say that I have never been the biggest fan of RPGs(though Final Fantasy 7 is an exception).  However in the case of Diablo II,  I love ehm.  It is a highly fun and entertaining game.  It revolves around the lands of sanctuary(sanctuary is the name of the world or section of the world).  Diablo,  the lord of terror, was once imprisoned in a soulstone along with his brothers, the lord of destruction and the lord of hatred(Baal and Mephisto).  However now he has been released and is shedding his terror and darkness over the world and of course you must stop him.  The Charecters:  You have the option of 5 charecter classes in Diablo II.  The Amazon:  A beautiful but deadly warrior from accross the sea.  She is a master at wielding bows and spear weapons.  Necromancer:  Raising the dead and cusring his enemies are his specialties.  The necromancer is one hell of a charecter.  He can, after slaying his unfortunate opponents, raise them from the dead as skelatons who fight for him(he can raise one skelaton per exp level).  Barbarian:  When it comes to fighting,  THIS GUY ROCKS.  A warrior from far away, ancient, not too mention heavily guarded, mountains, the barbarian is the ultimate charecter when it comes to meelee weaponry.  As he charges through he can shout great battle cries which can send his enemies running in fear, or leave them dead.  He can slaughter enemies mercilessly before showing signs of weakness, but his most impressive skill is the ability to wield to weapons at once, one in each hand.  With an ax in one hand and a sword in the other he can easily exterminate his opponents.
