World of Sea Battle

VS

Tower of Fantasy

World of Sea Battle is an indie open-world naval action game with RPG and simulator elements, developed by Thera Interactive. While it features open-world and multiplayer tags, the lack of wide recognition, a major publisher, and mainstream coverage suggests a small but steady niche community. Its indie studio background and limited marketing mean the player base is likely in the low hundreds daily. I do not classify this as a true MMO as there's no clear indication of massive concurrent player interactions.

Tower of Fantasy is a cross-platform open-world RPG released in late 2021 and published by Level Infinite (a Tencent brand), with significant investments in global marketing. Initially popular as a "Genshin Impact competitor," its player base peaked in its first year, but has since declined. It remains moderately active thanks to regular updates and events, especially in Asian markets. Given its age (over 2 years) and the usual drop-off for live-service MMOs, a conservative estimate is in the 50,000–100,000 DAP range globally.
