[upd] - Directplay

: DirectPlay Voice supported peer-to-peer and client-server voice chat with built-in compression. Evolution and Versions

DirectPlay was a valuable innovation in the late 1990s that democratized multiplayer game development. However, it has been technically obsolete for two decades. Its legacy lives on in the design of modern session-layer networking APIs, but direct use of DirectPlay today is inadvisable due to security, performance, and compatibility constraints. Preservation efforts for classic games increasingly rely on wrapper libraries that translate DirectPlay calls to modern UDP/WebRTC, rather than the original deprecated API. directplay
