Legends of IdleOn

Pokémon Trading Card Game Online was a popular digital adaptation of the Pokémon TCG, released in 2011. The game maintained a modest but dedicated player base due to the Pokémon brand, but its daily active player count declined after the launch of Pokémon TCG Live (which replaced PTCGO starting in 2023). The original client is no longer actively supported, and most of the active player base has transitioned to Live. Estimated daily players on the old service are very low, possibly only a few thousand globally, but the Pokémon TCG franchise remains strong overall.

Legends of IdleOn is a well-known idle MMORPG-style game released by indie developer LavaFlame2 in 2020. While it is not published by a major studio, it has maintained an active and dedicated community across multiple platforms (PC, Android, iOS). Its blend of MMORPG mechanics and idle gameplay has led to a steady, though niche, following, with daily active players likely around 10,000 based on player metrics from Steam, mobile downloads, and community engagement on Reddit and Discord. The persistent online world and large-scale player interactions do meet MMO criteria.
