Ni no Kuni: Cross Worlds

One Piece: Fighting Path is a mobile action RPG based on the popular One Piece anime, published by Nuverse and primarily popular in China and some Asian markets. Released in 2021, it saw a strong initial playerbase due to the IP's popularity. As a mobile gacha-style RPG with ongoing content, it's likely to retain a significant daily active population (estimated 200k–300k in active regions, as of 2024). Its scale does not fully meet MMO definitions—it is multiplayer but lacks a continuous, shared persistent world with thousands of simultaneous live interactions typical of MMOs.

Ni no Kuni: Cross Worlds is a mobile and PC MMOARPG published by Netmarble, released in mid-2021. It had a major launch, leveraging both the Ni no Kuni IP from Level-5 and gacha/MMO mechanics. The game peaked high but, like most mobile MMOs, saw significant player count decreases after the initial year. In 2024, it retains a dedicated but much smaller global player base, with estimated daily active users likely in the 50,000–100,000 range, especially due to its presence in Asia. Major publisher support and continued updates help maintain its relevance.
