Titan Quest

It is believed that at the dawn of time, there was a great war between the Titans and the Gods. During this war which spanned many centuries, humanity was born and stood beside the Gods. At the war's conclusion the Gods were victorious and the Titans were banished to the great darkness. Now the Titans have escaped and spread their evil over the ancient world of Greece (and beyond). You are a hero who arrives in this time of need to fight the Titans and bring peace to the world once more.

Not unlike Diablo or Sacred, Titan Quest is a hack 'n' slash Action-RPG in which you create a character and level up by killing thousands of monsters, like Hydras or Gorgons. At the beginning of the game your hero has no profession, but upon reaching level 2 you are given the choice between eight unique "masteries". Upon reaching level 8 you are granted access to a second mastery. This allows you the choice of creating a warrior who is good magician or a necromancer who can also kill his enemies quietly. If you feel that you've misspent your skill points, you can rearrange them (for a nominal fee) by visiting a certain NPC in each act.

The story of the game is based on the real mythologies of ancient Greece, Egypt, and Babylon, so you're bound to recognize many of your enemies. Additionally, you can learn much about the legends of the land you're adventuring in by talking to storyteller NPCs.

If you don't want to beat the hell out of the Titans alone, you can invite up to 6 friends and play in LAN/WAN with them in the cooperative mode through the entire game.
