Fishing Planet

Age of Water is a post-apocalyptic open-world game by Gaijin Entertainment (known for War Thunder). It released in early 2025, so it is still relatively new, but not a massive blockbuster. Gaijin's niche appeal and the open-world/sandbox elements suggest a moderate but not huge player base. Its MMO status is debated, but it appears to have persistent world and multiplayer interaction, fitting the basic MMO criteria; however, it is on the lower end of the active player spectrum for MMOs.

Fishing Planet is a free-to-play fishing simulator released in 2015, available on several major platforms (PC, consoles, mobile). Its niche appeal and simulation genre give it a modest but stable player base, bolstered by cross-platform play and regular updates. As a long-running, community-driven game, it likely retains an active core audience but does not approach the scale of top-tier online titles.
