Tanki Online

World of Sea Battle

Tanki Online is a browser-based tank shooter released in 2009 by Alternativa Games. While it was highly popular in its early years, its player base has declined over time due to age and increased competition. As a niche online action shooter with some persistent progression, it still retains a loyal but much smaller community, especially in Eastern Europe and Russia.

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.
