Fallout 76

Crush Depth: U-Boat Simulator is an indie, niche simulator released in 2021 on itch.io by a small developer. Submarine simulators tend to have a small, dedicated community but are not mainstream. Given its platform and lack of major publisher support, the daily player base is likely quite limited, under 100 players.

Fallout 76 is a 2018 online open-world survival RPG from Bethesda. After a rough launch, the game's player base stabilized thanks to consistent content updates and improvements. While its concurrent popularity never matched leading MMOs, its cross-platform presence and support allow it to maintain a smaller but steady loyal community. As of 2024, daily active players are estimated around 30,000–40,000 based on public sentiment, recent expansions, and visible in-game activity, particularly after updates or events.
