IdleOn

Age of Empires Online: Celeste Fan Project is a fan-run revival of the original Age of Empires Online, which was discontinued by Microsoft. As a community project launched in 2017, it maintains a niche but active RTS player base, mostly composed of dedicated fans. While not as popular as mainstream RTS games, its weekend activity peaks and ongoing support likely keep daily active players in the low thousands range. It is not run by major publishers but has support from a dedicated fan community.

IdleOn (Legends of IdleOn) is a niche indie idle MMORPG released in 2020 by solo developer LavaFlame2. While 'indie' and 'idle' games generally have moderate daily activity compared to AAA titles, IdleOn maintains a loyal fanbase due to its unique persistent-world idle mechanics and multi-platform availability. Its activity is bolstered by regular updates and a dedicated community, but as a non-mainstream MMO, it likely sustains around 30,000 daily players at present.
