Age of Water

Florr.io is a browser-based indie action game released in 2020 by Matheus Valadares, known for creating other successful io games like diep.io and agar.io. While past io games had massive player spikes, Florr.io's current active player base is significantly lower given its age, niche appeal, and the general decline of the io genre after their peak, but it maintains a dedicated community. A conservative estimate considering ongoing casual traffic is about 10,000–20,000 daily players.

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.
