Core MUD

Star Citizen

Core MUD is a text-based multi-user dungeon (MUD) launched in 1996, when MUDs were popular among early internet communities. Today, almost all MUDs see very low concurrent activity due to their age and the niche appeal. Based on the genre's decline and absence of a major publisher or active social channels, it's likely Core MUD maintains a very small, dedicated player base.

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.
