Star Wars: The Old Republic

Doomsday: Last Survivors is a mobile-focused real-time strategy survival game published by IGG, known for other long-running titles like Lords Mobile. While it's several years old (2021 release), similar IGG games tend to maintain a stable, mid-sized userbase through aggressive marketing and frequent updates. The game's active presence on multiple platforms (Android, iOS, Windows) and social media suggests continued engagement, though likely below its peak. Not an MMO, as its multiplayer is lobby/guild-based rather than a persistent shared world.

Star Wars: The Old Republic is a classic MMORPG launched in 2011 by BioWare and published by Electronic Arts. Although it had a large player base at launch, the numbers have declined over the years, especially since it's now over a decade old and several expansions have come and gone. However, it still maintains a loyal core community thanks to regular content updates and the strength of the Star Wars IP. As an MMORPG, it does meet the MMO criteria with a persistent online world and the ability to interact with thousands of players simultaneously.
