...Odyssey is a fairly basic hack and slash ORPG (Online Role Playing Game). It is designed to run on lower end computers, some as slow as 66mhz. Instead of focusing highly on visual, and aural elements, Odyssey tends to focus on gameplay value, and replayability.
"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 was started in the mid-90s and is widely said to be the first successful VB6 MORPG.
