Knight Online is a MMORPG that is fully 3D and has outstanding graphics for a freeware game. You can form a party with other players and fight monsters to level your character or complete quests. You can choose to be either an Orc or Human, and they occasionally have wars between the two species.

There seems to be different versions of this game. The one I listed is USKO, the United States version. Others exist and for the most part are the same, with slight differences in prices of items and experience from killing beasts. Play whatever one you want, because it is the same game, but know that your character will not port to another server.
