The Castle Doctrine is an indie strategy/puzzle game released in 2014 by Jason Rohrer. It had a niche appeal and limited multiplayer features, with activity declining sharply over years. Due to game age, indie scope, and lack of recent major updates or promotion, the active player base is now extremely low—likely fewer than a dozen daily players.

Diep.io is a browser-based action-shooter released in 2016, known for its simple but addictive gameplay and popularity among casual gamers. While its peak was years ago, it retains a niche audience due to easy access (browser/mobile) and support from publishers like Miniclip and Addicting Games. Modern estimates suggest that around 10,000-20,000 players still play daily across web and mobile, typical for older .io titles.
