What is Idle RPG?

An “Idle RPG” is a distinct subgenre of role-playing games (RPGs) characterized by its passive or automatic gameplay design. In an idle RPG, player interaction is intentionally minimized, and in some instances, not necessary at all. Instead, the game unfolds autonomously, with the player’s primary role typically revolving around initial setup, strategic decision-making, and occasional interaction with the game’s mechanics.

Idle RPGs are popular on mobile devices, primarily attracting players seeking a more relaxed gaming experience or those who appreciate the ability to advance within the game without the need for constant active participation. These games often give off a casual and soothing atmosphere while retaining captivating elements related to character development and strategic decision-making.

The global expansion of Idle RPG

Idle RPGs have been experiencing remarkable growth on a global scale, with a particularly noteworthy surge in popularity observed in South Korea. This surge is part of a continuous upward trajectory that idle RPGs have been following over the past four years. By analyzing revenue and download data spanning from January to September for four years since 2020, a consistent pattern of growth has emerged.

*Note: Based on annual January-September data for comparison. The overall game market ranking is based on the number of revenue or downloads among the 86 Sensor Tower game taxonomy subgenres.

In the mobile gaming landscape, idle RPGs moved up the ranks, climbing from the 69th spot in downloads from January to September 2020 to the 59th position within the same timeframe in 2023. Within the RPG subgenre, idle RPGs made up 7.5% of downloads in the initial period but have since seen substantial growth, accounting for 10.4% in 2023.

However, it’s in South Korea where the most striking growth has taken place. South Korea, a traditionally strong market for RPGs, has witnessed a significant rise in the popularity of idle RPGs. According to Sensor Tower’s data, these games have ascended from the 42nd spot to the remarkable 2nd position in downloads in the overall gaming market. Within the RPG genre, idle RPGs have seen an even more impressive increase, shifting from 4th place in 2020 to the leading position in 2023, capturing a substantial share of 28.2% in downloads.
