FutureMUD is a MUD Engine for RPI MUDs written in C#, begun in 2009 by Japheth and Case in C++ (WinMUD) and later re-implemented in C# (MudSharp) in 2012. While it is presently a closed-source project, the end goal is to create a free, stable, powerful MUD Engine that has a less restrictive license than the DikuMUD license upon which most RPI MUDs are built today.
