One Piece: Fighting Path

Scum

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.

Scum is a multiplayer open-world survival game developed by Gamepires and originally entered Early Access in 2018. While it is not a full MMO, it supports servers with dozens of players (up to 64 per server). The game maintains a niche but dedicated following and is frequently updated; however, it has never reached large mainstream status. Based on long-term trends of similar survival games, its daily active player base is estimated to be in the low thousands, and this estimate would hold unless a major relaunch or expansion revitalized the player base.
