Star Wars: The Old Republic

Gunslinger Stratos is a Japanese arcade shooter released in 2012, published by Square Enix. The game is primarily played in arcades and is not an MMO by standard definitions. Given its age (over 10 years since release), niche arcade-only presence, and lack of recent updates, the active daily player count is expected to be quite low—contingent mostly on a few remaining arcade machines in operation, mainly in Japan.

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.
