My single server hosts 250+K active players in one giant, dynamic fantasy world. Angeldust's game server is pervasively multithreaded, implementing John Carmack's dream of processing an immutable world state each tick.

Both world handling and network traffic routing uses any number of threads. For networking, a typical game session only uses ~3Kbps of bandwidth, enabling decent play even over 2G/EDGE networks.

The client is programmed in C++ with bits of C, Objective-C, Java and PHP. It runs really well on very low-end and obsolete hardware, all the way up to modern systems with fast GPUs.

Angeldust works perfectly on Windows XP+, even without hardware OpenGL; Mac OS X 10.6+, even on the first 2006 32-bit Intel GMA945 MacBook1,1; Linux 64-bit glibc 2.17+; Android v2.2.3+, supporting Bluetooth game controllers; and iOS 6+, though iTunes App Store forces iOS 8+ (any way around this?).

I live stream weekly on YouTube and Twitch, even right now! Come ask me your development questions! I often see developers playing together with their kids.

One more thing: the Angeldust website ( https://angeldu.st ) uses plain HTML and CSS to offer interactive, game-related actions. It's fully functional even without JavaScript enabled.
