Priston Tale is a 3D fantasy MMORPG that centres on action-based role-playing. It was originally released in South Korea, 2001, by Yedong Online. It was created by Triglow Pictures Inc. (now known as Priston Inc.) and has since been published for Japan, China, Taiwan, Thailand, Vietnam, England, Philippines, Brazil and the Spanish-speaking countries. In 2004, the English version of Priston Tale went out of public beta (in which it had remained for nearly 2 years) and became a commercial pay-to-play game. On May 17th, 2007, Priston Tale announced free-to-play service for everyone; instead of paying for the game, Priston Tale has a cash shop in which players can pay real money for game items. As of September 30th, the English server for Priston Tale will close and a new Canadian Company Subagames, will resume service for the English server.

Some of the features of Priston Tale include a clan system, in-game shops, eight character classes - all of which can use every item available if they have the correct upgraded statistics (with the exception of armour, robes, and orbs) - a four-tiered skill system for each class, item upgrades, a simple yet involving battle system and an easy to use interface. Priston Tale is also intensive in potion using, and dying is moderately easy. The experience loss per death also tends to climb quite steeply (experience loss is based on a percentage of obtained experience), mirroring the ever increasing experience needed to level.

Throughout the game, the characters progress through a series of levels and acquire skill points. As they progress they get different items, such as weapons and armour, to help them in their quest of achieving the ultimate warrior. Items of this calibre usually require a larger amount of skill points in an area than the previous items. Armour in general helps the character stay alive longer by giving them different attributes. Weapons in general help the character defend themselves or attack any monster they wish with a lot more force. At the same time, there are certain specifications as to when players may use such weapons and armour. These are mostly based on level and stat requirements. Also, there are certain specs for armour and weapons so that they may achieve their great performance and special stats. These may be found in game, written on the armour or weapon. (E.G. Fighter Spec, Knight Spec, etc.) Different Classes use different weapons; for example, the knight mainly uses two-handed swords and blades, whereas the Archer uses bows. The different items players may obtain with specs determine which types of character classes use them. Most swords will come as Knight or Mechanician spec when most wands/staves will come as Magician Spec or Priestess Spec.

Currently, Priston Tale 2 has only been released outside of beta in Korea. Player response in Korea has been very good, with over 30,000 players online simultaneously on the 1st day of open beta, and 40,000 players online simultaneously as of the 3rd day. The game still maintains popularity and is competing with SP1 and Twelve Skies for market share, with tens of thousands of players online simultaneously at any given time.

Priston Tale received an award for "Outstanding Online Game" in December 2002 and "Outstanding Programming" at the 2003 Korean Gaming Grand Ceremony.
