Star Wars: The Old Republic

Age of Water is a post-apocalyptic open-world game by Gaijin Entertainment (known for War Thunder). It released in early 2025, so it is still relatively new, but not a massive blockbuster. Gaijin's niche appeal and the open-world/sandbox elements suggest a moderate but not huge player base. Its MMO status is debated, but it appears to have persistent world and multiplayer interaction, fitting the basic MMO criteria; however, it is on the lower end of the active player spectrum for MMOs.

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.
