Block Story

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.

Block Story is an indie sandbox RPG released in 2015, somewhat inspired by Minecraft but with RPG and adventure elements. Its initial popularity has significantly declined over the years due to its age, lack of major developer presence, and limited mainstream attention. As an older indie title with mainly single-player or small-scale multiplayer features, it now likely retains a very small, dedicated player base across platforms.
