One of the top three mobile games released by Gameville, along with the 'Com2uS Pro Baseball' and 'Nome' series, when it was not part of Com2uS. The first work of the 'Zenonia' series, 'Zenonia: Thread of Memory', was registered on Steam under the name 'Zenonia 1'.

Zenonia 1 was released in August 2008, and could be purchased and played for an information usage fee of 3,000 won at the time. This work, released with the catchphrase 'Reality Action RPG', adapted to the smartphone environment released later and enjoyed popularity with versions developed for NDS and PSP.

Afterwards, the success of the first Zenonia became an opportunity to create a sequel to the series, and it became a long-running series with 5 numbered titles and a total of 9 works including spin-off works. However, this also faded over time, and in the case of Zenonia 1, which is being re-introduced this time, service ended on December 19, 2014, and there was no way to play it except for the console version and direct download of the APK.

Zenonia 1 registered on the Steam page is basically the same as the existing game, but has been updated in terms of graphics and UI. Players can train the main character 'Rigrit' into one of the following: a 'Warrior' with balanced performance, a 'Paladin' with strong defense, and an 'Assassin' with lethal attack power. It is equipped with a day/night system that changes over time and a good/evil system that changes depending on the player's choices.

However, the release date and price of Zenonia 1 have not yet been revealed.
