World of Sea Battle

VS

Realm of the Mad God

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.

Realm of the Mad God is a browser-based, free-to-play MMO bullet hell shooter first released in 2011. While its peak passed years ago, it still maintains a niche but active player base thanks to frequent updates from DECA Games and its unique gameplay loop. As an indie MMO, it is unlikely to have more than 10,000 daily active players but retains a dedicated community.
