Odyssey Classic Online is a 2d top-view online RPG that is set within a medieval setting. There are several player classes available and it is both PvP and quest based. "The Odyssey Engine" is the sole inspiration for many other games such as the original "Mirage Online", which ultimately transformed the ease of Online RPG creation with the Playerworlds program. The Odyssey Classic was started in the mid-90s and is widely said to be the first successful VB6 MORPG.
