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.
