Oort Online

Star Citizen

Oort Online is the original title for what later became 'Boundless,' a sandbox MMO developed by Wonderstruck Games. As Boundless, the game launched in 2018 and has since maintained a niche community. However, its daily player base is quite small due to its age, limited marketing, and niche appeal. It still has elements of a persistent world and large-scale multiplayer, thus fitting the MMO definition, but its active player count in 2024 is likely under 200 per day.

Star Citizen is a highly ambitious, persistent online sci-fi universe developed by Cloud Imperium Games and in development since 2013. The game maintains strong interest due to continuous updates and community engagement, though it's still in alpha. Its daily active players generally range from 30,000 to 60,000, despite being niche compared to mainstream MMOs, but with a loyal playerbase and steady developer communication.
